CONSTRUCTION MONITORING AND NUMERICAL SIMULATION FOUNDATION OF A ANALYSIS PIT

Sun Kai1,Xu Zhengan2,Liu Tingjin3,Fang Zongxin1 (1 Haikai Construction Engineering Limiter Company of Hainan Province, Haikou 570216 China) (2 Architecture Design and Research Academy of Guangdong Province, Guangzhou 510010 China) (3 Department of Geotechnical Engineering,Tongji University, Shanghai 200092 China)  
Firstly,the design of retaining and protection structure for foundation pit is introduced based on slipping mechanics model and elastic foundation beam model. Secondly,the feasibility of CSC method and retaining and protection structure is analyzed,according to monitoring data in situ. Finally,the staged construction process of foundation is simulated by using Tongji University GeoFBA FEM software. The results of field measurements and numerical simulation indicate that prestressed anchor cable and pile-retaining-and-protection structure can effectively control the foundation deformation and surface settlement.
