Foundation pit dewatering of foundation pit excavation and foundation construction, there is no water running create conditions to ensure the effective excavation construction, and weaken the influence of the environment in the process of excavation. Groundwater improper handling of the formation of unhealthy phenomenon is mainly the internal and external water head difference the reason of the pit wall, unreasonable or non-standard dewatering well construction, seepage resistance difference of the support structure, the surrounding water invasion, etc. At the same time, because of the influence of the deep foundation pit construction management and engineering projects and the special characteristics of various uncertain factors, project implementation will be there is the opportunity and the possibility of deviating from the expected purpose, namely, there exists a crisis. Held for deep foundation pit engineering risk analysis is not to cut and control risks should be on the basis of the analysis, to control risk and governance.
