Natural Disaster Risk Monitoring for Immovable Cultural Relics Based on Digital Twin

Natural disaster risk monitoring is an important task for disaster prevention and reduction.In the case of immovable cultural relics,however,the feedback mechanism,risk factors,monitoring logic,and monitoring indicators of natural disaster risk monitoring are complex.How to achieve intelligent perception and monitoring of natural disaster risk for immovable cultural relics has always been a focus and a challenge for researchers.Based on the analysis of the concepts and issues related to the natural disaster risk of immovable cultural relics,this paper proposes a framework for natural disaster risk monitoring for immovable cultural relics based on the digital twin.This framework focuses on risk monitoring,including the physical entities of natural disaster risk for immovable cultural relics,monitoring indicators,and virtual entity construction.A platform for monitoring the natural disaster risk of immovable cultural relics is proposed.Using the Puzhou Ancient City Site as a test bed,the proposed concept can be used for monitoring the natural disaster risk of immovable cultural relics at different scales.

Design and Construction of Topographical Elements in Parks of Historical Relics

The protection and utilization of great historical sites mainly includes 4 modes,specifically,building the whole site into a park of historical relics;combining the site with the scenic area into a tourist site;building the site into a forest park;combining site protection with development of modern agriculture so as to build an agricultural park of historical and cultural relics.In this study,it was emphasized that landscape design of such parks should first be based on the protection of historical relics.Among all constructed parks of historical relics in China,Relics of Sweet Spring Palace,Tomb of the Military Marquis Zhuge Liang and Mausoleum of the Yellow Emperor were taken as examples to demonstrate how large-scale topographical elements form the spatial pattern of garden landscapes;Ruins of the Old Summer Palace and the Park of Qujiang Pool Relics were taken to show how moderate-scale topographical elements form the spatial division of garden landscapes;by giving examples of micro-relief slope utilization,micro-relief stone and water layout,utilization of original reliefs and micro-relief functions,this study illustrated how such micro-scale topographical elements form landscape nodes in gardens,and specifically introduced functions of micro-relief,such as dividing and controlling spaces,creating aesthetic value,improving micro-climate and so on.Moreover,cases of terrain utilization and creation in classical western gardens were given,and masterworks of some modern western garden designers were borrowed and analyzed to find valuable concepts for designing parks of historical relics in China.

Environmental Renovation and Improvement Strategies for the Great Relics——A Case Study of Landscape Planning for the Front Hall Relics of the Weiyang Palace in China

Through introducing concepts of great relics and its protective planning theories, construction of relics park is a characteristic protection mode for cultural heritage in China, and also a useful exploration in the combination of theories and practices of great relics protection. Moreover, it is also the best means of protecting great relics ever found. Taking landscape planning of the front hall relics of the Weiyang Palace, relics of the front hall was believed to have great scientific value, so its environmental renovation and improvement should be based on scientific landscape planning, the whole relics should be protected and displayed scientifically and completely, landscape elements introduced as the effective texture by applying ecological patterns according to actual conditions, new techniques favorable for the protection and scientific research of relics adopted to provide a new strategy for the construction of great ruins park in China.

Glacier Relics of the Last Glacial and Holocene Periods Discovered in the Middle-low Mountains of Eastern China: Sedimentary Sequences and Environmental Evolution of Mengshan Mountain in Shandong Province since 80 ka

The goal of this research study is to describe academic issues which have been debated in the field of Chinese geosciences for a century. In 1922, Jonquei S. Lee(Li Siguang) discovered Quaternary glacial relics at Taihang Mountainin eastern China. In 1947, he published his research findings in the magazine Mount Lushan in Glacial Age. The research results had established three Ice Ages: Poyang(Gonzi), Dagu(Minde), and Lushan(Lisi). However, at that time, no Wurm glacial relics of the last Ice Age had been found in Lushan Mountain. Since then, the research team represented by Shi Yafeng, who is considered to be "the father of glaciers in China", questioned Jonquei S. Lee’s research results and concluded that "Professor Jonquei S. Lee’s Quaternary glacier research in Lushan Mountain having misread the debris flow". In 2005, the "middle-low mountains" in eastern China were finally defined as follows: "We clearly and unambiguously believe that there were no glacial activities in the middle-low mountainous areas of eastern China(east of 102° to 104°E;below 3,000 and 2,500 m) during the Quaternary Period". Currently, the long-standing academic debate appears to have come to a conclusion. As of 2015, the author and others began to investigate and study the Quaternary glacial relics in Mengshan Mountain(1,156 m above sea level), Shandong Province, one of the "middle-low mountains" of eastern China. The relics have been observed to posses the systematic features of glacial erosion, trough and valley striations, and moraine deposits. The applied dating method shave confirmed that there were not only glacial relics of the last Ice Age(Wurm), but also Holocene glacial relics in the Mengshan Mountain area. Therefore, in order to further establish the corresponding relationship between the glacier, loess, stream sediment series, and MIS in the Mengshan Mountain area, a large number of chronological studies have been carried out regarding the various types of sediments in the area, and 24 dating datahave been obtained using OSL, CRN, and 14 Cmethods.On this basis, the corresponding relationship between the sedimentary sequences and the MIS was established for the first time in eastern China, which in dicates the environmental changes which had occurred in eastern China since 80 ka. These discoveries s and chronological study results confirm the existence of the Last Ice Age, as well as Holocene glacial relics at Mengshan Mountain, there by confirming that Quaternary glaciation had occurred in the middle-low mountain areas of eastern China.

Aseismic strengthening techniques of Chinese typical stele relics:A case study of Xi'an Beilin

In order to improve the seismic performance of Chinese traditional stele relics, a suitable aseismic strengthening method of Chinese traditional stele relics is proposed. Taking the typical stele relic in Xi＇an Beilin as an example, the on-site investigations were carried out to obtain the actual geometric size and damage state of the stele relic. Then, the structural performance of the stele relic was analyzed by the finite element software ANSYS. Finally, the two different aseismic strengthening methods of the traditional stele relic are proposed and comparatively analyzed. The results show that in addition to the common problems, such as weathering, and cracks, etc, earthquakes seriously threaten the structural safety of stele relics. Under the rarely-occurring earthquake of eight degree, the unstrengthened stele relic will be overturned, and many cracks will occur at the connection area of stele body and stele pedestal. When the stele relic is strengthened by the stainless angle steel strengthening method, the stele relic will not be overturned, but some cracks will occur at the connection area of stele body and stele pedestal. When the stele relic is strengthened by the base isolation strengthening method, the stele relic will not be overturned, and no cracks will occur at the connection area of stele body and stele pedestal. Therefore, the aseismic strengthening effect of the base isolation strengthening method is obviously better than that of the stainless angle steel strengthening method, and this method is a suitable aseismic strengthening method of Chinese traditional stele relics.

Value Analysis of Immovable Cultural Relics from Landscape Perspective

This paper started by defining immovable cultural relics and landscape, and explicitly classified cultural relics under landscape. Then it analyzed the scientific value, artificial value, and historical value of cultural relics based on the angle of landscape. All these values had been changed and were indicated cultural value, aesthetic value and resource value as new values. The cultural value included identification with culture, inherited culture and educational value. The content of aesthetic value contained visual aesthetics and enjoyment. The resource value which was composed of the essence, space-time and scarcity, was revealed economic value, which was composed of environmental value and tourism value. In the following, the values of landscape and the new identified values of cultural relic were compared together to discover the connections between them. Finally, the new values of cultural relic were established under the angle of landscape which was composed of 4 degrees.
