Research on Optimization of Foundation Pit Support Scheme under Complex Environmental Conditions
The selection of foundation pit support scheme is closely related to geological conditions,surrounding environment and other factors.Taking a deep foundation pit project in Longyan,Fujian as an ex-ample,the original support scheme of the foundation pit has the problems of complex construction technolo-gy and high cost.Combined with the surrounding environment of the foundation pit,the depth of the founda-tion pit,the geological conditions,and the lack of the original scheme,the optimization strategy is proposed from the aspects of the overall scheme,local reinforcement,drainage system,construction coordination,and foundation pit monitoring.The original support scheme is optimized to achieve the purpose of technical feasibility and economic rationality.The practice results show that the optimization scheme has completed the foundation pit construction with quality and quantity within the established construction period,which saves 80%of the cost cost compared with the original side,and the effect is remarkable.It has certain refer-ence function for the optimization of foundation pit support scheme of similar projects.
