Water conservancy engineering construction enterprises should refer to oneself circumstance, and the characteristics of the water conservancy project, determine the quality objectives of specific quality assurance plan and the related measures, clear implementation content, methods and effects. Strictly control the factors influencing the water conservancy engineering quality of many aspects, in the process of the water conservancy project construction, to establish a meet the requirements of the technical process and quality standards, operation procedures. Establish the strict appraisal system, continuous improvement and improve the level of construction technique and technology. Establish strict quality assurance system and quality responsibility system, each division, subdivisional work will comprehensively implement in place management to ensure the engineering quality.展开更多

Some examples of heritage abuse are given alongside some innovative ways of presenting relics of the past to society. Methodology consists in the scrutinizing of chosen examples, selecting conclusions and a synthetic presentation of research results. The aim is proper protection of historic architectural resources through documentation and dissemination of knowledge. First part is concerned to rejection of old aesthetics values and implementing a new one on example of Brussels＇ House of the People （the largest work by Victor Horta that opened on 1899 and demolished in 1965 despite a protest of architects） and ridiculous renovation in Krynica, Poland. In second part, it presents tree examples of successful implementation of innovative techniques and technologies as the Pauline fathers realizations of renovation sacred architecture （churches, cloisters）, also valuable digital projects of the reconstruction of the vaults and realization of underground Museum in Krakow, Poland （the outstanding creation of the atmosphere of virtual historic reality by the latest audio-visual techniques）.展开更多

The system mainly includes digital dam, three-dimensional design, construction quality monito- ring, safety assessment and warning, etc, to integrally manage and analyze the dam design, constructional quality and safety monitoring information. It realized the dynamic updates of the comprehensive information and the safe- ty quality monitoring in the project life cycle, and provided the basic platform for the scientific management of the construction and operation safety of high earth-rock dam. Application in Nuozhadu earth-rock dam showed that construction safety monitoring and warning greatly helped accelerate the construction progress and improve project quality, and provided a new way for the quality safety control of high earth-rock dam.展开更多

At present, debris-flow prevention has performed well in many mountainous countries and has made headway in early warning, disaster mitigation by structural engineering methods, and risk analysis and management. In this paper, debris-flow prevention techniques have been introduced from the aspects of botanical methods, geotechnical engineering methods, and synthetic prevention system based on the above two methods. In addition, the treatment system of multilevel runoff and unconsolidated soil in the catchment with a chain of ＂slope-gully-valley＂ is set up in consideration of sediment load of main rivers, incorporation of slope improvement and gully retention, as well as micro-site factors for matching species with the site. Furthermore, attentions should be paid to the mechanism and technical details of vegetation measures for debris-flow prevention, as well as effective incorporation between botanical method and geotechnical method.展开更多
