VC常见的108个问题(国外英语资料) Disaster and disaster relief of continuous wall Shen Maosong / Professor, Department of civil engineering, national Kaohsiung University of Applied Sciences The standard penetration test and the number of NSPT is less than or equal to 4 moisture content than liquid limit LL soft clay silt with NSPT less than 10 of the loose sand sites, and more than two kinds of soil layer into the site, or collapse hole in the continuous wall construction, and with the continuous wall of concrete mixing, resulting in a continuous wall, mud bag bag, mixed mud and sand clods of the chain of Engineering disaster. The site of continuous wall cladding can be classified as four A, B, C and D sludge sites. The catastrophic time of retaining excavation is judged by an example. The failure time of clay clay swelling is about 12~13 hours, and the time of sand drift for sandy soil is about 1 hours. The continuous wall site in addition to underground excavation occurred when mud packs damaged, damaged adjacent engineering disaster, continuous wall is designed for permanent basement exterior wall structure of the site, after the project is completed and in use for many years after the building, will damage and damage disputes. In this paper, a case study is carried out to analyze the engineering disaster after the continuous wall breach and the emergency relief method on site, so as to accumulate the knowledge of emergency rescue of basement engineering, and to serve as a reference for retaining excavation excavation. Shen Maosong [1] pointed out that as an underground continuous wall excavation of temporary retaining wall, even as a permanent wall structure design used in the basement, the soil is loose, will produce a package of mud, dirt, mud and mixed bag sand and other chain engineering disaster, and continuous wall in different periods of mud pack seepage damage the disaster caused by the project, such as roads, the adjacent building base near the settlement and dumpin
