The Space Analysis of Soft Soil Excavation by using the rule of TSE

Fan Yiqun et al.  
In this paper, the space computation model on frame bracing system by using the rule of Time-Space Effect(TSE) ,and its finite element sub-structure technique are proposed based on the previous work~[3] and the many years results of Shanghai Time-Space Soft Soil Engi-neering Research Consultant Center~[1-2] The computer codes which discribe the incremen-tal process have been programmed. With the application of the method to a practical engi-neering example, it is indicated that present model can be utilized to simulate the excavation process with high efficiency and to give good results of the stress and deformation distribu-tions in the braced structure. Also the secondary stress of bracing system induced by the de-formation of nodes can be considered. This work is significant to the study of controlling ground movement around deep excavation in Shanghai soft soil.
