Coastal Soft Soil Deep Foundation Pit Supporting Technology Research And Application

The beginning of the foundation pit supporting technology is first arose abroad,in the early 1930 s began to dabble in and made some progress.Relatively late in our country,at the beginning of the reform because most for small ground buildings,foundation pit depth did not achieve the depth of the need to support.After the reform and open policy,our country economy has obtained great achievement,all walks of life are all in great prosperity and also from the initial small building construction industry in our country to develop modern high-rise or landmark buildings,but in the early because most for small ground buildings,foundation pit depth did not achieve the depth of the need to support,so the foundation pit supporting technology in China has not been substantial development.Into the 80 s after the reform and opening up,accelerating the urban construction and technical requirements for the construction industry practitioners continue to improve,especially in the 21st century,high-rise building iconic large buildings,underground space engineering,and the corresponding foundation pit engineering also become hot.Linhai city walk in the forefront of the economic development,in particular,such as shenzhen,Shanghai,tianjin,more rapid development,the land resource is extremely scarce,they are more urgent demand for high-rise buildings and underground buildings,they expect more buildings,deeper underground space,more effective methods of land resource utilization.Linhai city but mostly is the characteristics of soft soil,soil of foundation pit supporting project put forward higher technical requirements,so research of coastal soft soil foundation pit supporting is a hot and difficult in foundation pit problem,the coastal soft soil deep foundation pit supporting technology have very strong realistic meaning of research and application of.Paper to near bohai sea of cangzhou city as the background,a deep foundation pit engineering example analyses the design method of soft soil deep foundation pit supporting and inspection method,analyzes the preliminary exploration of soil in the important position of supporting design,linhai deep foundation pit dewatering design and verification,the method of data simulation and optimization scheme of supporting design scheme,test the monitoring programme in the role of information construction,combined with the construction of the practical effects of the test data analysis support scheme summary data to provide experience for similar engineering design and construction of future,the study of similar soft soil deep foundation pit has very important significance.
