The main structure was severely damaged. In order to understand its current structural properties and provide a scientific basis for protection design nonlinear finite element analysis and parameter analysis are carried out.The crack patterns deformations and stresses of the main structure under four load cases are analyzed by nonlinear finite element analysis and the effect of the backfill bulk density and modulus on the maximum principal tensile stress and maximum compressive stress are studied by parameter analysis.The results show that the most unfavorable condition for the foundation is the combination of weight＋backfill soil pressure＋additional load the most unfavorable load case to the main structure is weight ＋backfill soil pressure ＋water pressure＋additional heap load the maximum principal tensile stress of the main structure is very sensitive to the changes in the bulk density of the backfill soil.展开更多

Then, the authors make it clear the strategies to be adopted for solving the existing traffic problems in the ancient urban area of Suzhou(AUAS), namely insisting on the goal based strategy; the strategy to develop the public transit system in priority and decreasing the demand on cars from the view point of land use strategy. On the basis of such analysis the authors put forth proposals about major measures to be taken to improve traffic conditions of the AUAS, such as construction of express artery ring around the ancient city, appropriate transformation of the roads in the AUAS and rational distribution of car parking areas at the outskirt, which are of positive significance in guiding the protection of the AUAS and transportation construction. In this paper, specialized software is used to establish criteria for the construction scale and extent analysis and evaluation of the ancient city construction project, which is of some reference significance to the transformation of old urban areas in other cities.展开更多

In periods of Song and Yuan Dynasty, it had become important geographical indication and port wharf of Guangzhou, because it is located in the main waterway. In Ming Dynasty, Pazhou Tower had become the symbol of the country in local area which was built by Guangzhou gentry. After Qing dynasty, with the raise of Ancient Huangpu Harbor, Pazhou village had a greater influence. Pazhou Tower and Temple had become well-known scenic local attractions, which was one of the ＂Eight Top Scenic Spots in Guangzhou＂.展开更多

Over 200 works were put on display at the Kimbell Art Museum that revealed the formative years in the French painter＇s works. The drawings and paintings confirmed Poussin as the leading classicist in 17th century French art and expanded our appreciation of the flexibility of the artist to illustrate mythological narratives. Previous positions on the artist such as Anthony Blunt＇s, who viewed the painter as a strict classicist without a major interest in color, are now reevaluated after the Fort Worth show. The influence of the Venetian school, especially the work of Titian, emerged stronger into Poussin＇s oeuvre. It was under the classicist umbrella that the romantic verse of Ovid and the sensual color of Titian became forged into the pictures of Roman mythology. The leading source of inspiration for this work would be Ovid＇s Metamorphoses where figures change into flowers made timeless by the painter＇s brush. Just as the poet varied the structure of his narrative presentation, so too did the painter expand his approach to depicting scenes of change in a variety of formats. A key work for Poussin in these stories of change would be the Kingdom of Flora （1631） where Ovidian tales are posed as an eternal spring where the goddess distributes the flowers of the collective narrative in an olive green chitin. This paper will contribute to the position of viewing Poussin＇s art under a wider vision of classicism where flexible narrative design and sensuous color fit the mission to make art noble and timeless.展开更多
