Back Analysis Of Displacement Of Seep-stopping Wall In Deep Excavation Based On The Elastic-Plastic Finite Element Theory

Safety Monitoring of civil engineering is a process,which includes exercising monitoring machines and operations to measure the project's important parameters or its all around termly,and then analysis the datum in order to make a judgement. Due to the projects'particularity and complexity,it's difficult to feedback and evaluate the construction's Safety coefficients. Firstly,author has fully reviewed the development of research in back analysis area.then,taking some of methods to find out the seep-stoping wall's physics and mechanics parameters by back analysis what bases on monitoring data in the Sha Wan hydraulic power station project. Aiming at the deep excavation project's character , author has researched both Elastic-Plastic Finite Element theory and the antilogy of model building.the Bi Ship Method and Intensity Reduce Method of Finite Element also has been used in analyzing the stability of the excavation's border.The author has completed the following works:1. Firstly the author has fully researched the method of back analysis and safety monitoring ,taking a power station as background, to emphersize the rationality of collocation in safety monitoring .2. Combining with the practically engineering ,particularly introduced the elastic-plastic finite elements theory and built a finite element model ,which can...
