摘要
采用三维有限元法对围堰竣工期和正常蓄水期的应力变形进行有限元分析计算,给出了不同时期堰体、堰基和不同材料、厚度防渗墙的应力变形结果,通过计算分析来判断堰体结构的安全度,校核防渗墙的强度,所得结论可为同类工程设计和优化提供参考。
The three-dimensional finite element method is adopted to analyze the stress and deformation during the period of cofferdam＇s completion and normal impounding,giving the results of the stress and deformation of the cofferdam body and cofferdam foundation in different periods and the cut-off walls of different materials and thickness,and then judging the cofferdam structure＇s safety degree and checking the strength of the cut-off walls.The conclusions can provide references for the design and optimization of similar engineerings.
