深基坑支护方案优化设计及有限元分析The 深基坑支护方案优化设计及有限元分析 The optimization design and finite element analysis of deep foundation pit support scheme Abst ract In China,deep foundation pit excavation and supporting engineering began in the 80s． With the development of high-rise building in the city，the depth of the foundation pit excavation is also increasing and more and more difficult．After entering the 90s，such as excavation and supporting of deep foundation pit engineering has become one of the hot and difficult problems in industrial construction．Deep foundation pit supporting and excavation is a high-risk systems engineering，because there are tOO many influencing factors，such as Deep foundation pit supporting and excavation is a high-risk systems engineering，because there are too many influencing factors，such as the surrounding environment and conditions excavation， ground water treatment，construction process，monitoring and control measures etc．Excavation and supporting of foundation pit engineering involves with geotechnical engineering，structural engineering and drainage engineering，etc．，which is such a comprehensive discipline．It iS crucial to make sure the foundation pit support system iS stable and deformation of Deep foundation pit meets the requirements of the surrounding environment before making reasonable design of foundation pit supporting,which includes selecting，and optimizating the plan of foundation pit support，structure design of foundation pit supporting and construction process．Solving the above problems is of great practical significance，and which is a scientific precondition and fundamental guarantee to ensure the safety，economy and scientifc of construction． This paper mainly completes the following content：this paper expounding the research background and significance of the foundation pit engineering，discussing the development trend of foundation pit engineering．According to the characteristics of the foundation pit engineering to figure out the needs of sat
