有限元分析双排桩在基坑支护中的应用

On application of finite elementary analysis double-row piles in foundation pit support

通过GeoStudio处理软件,对双排桩在基坑支护中的应用进行非线性有限元分析,综合考虑基坑开挖边界条件、开挖分期施工工程中参数的变化及双排桩受力特点,从计算结果中分析基坑的应力及双排桩的受力,从而可以得出用有限元法分析双排桩及双排桩在基坑支护中应用能达到良好效果的结论。

According to the GeoStudio treatment software,the paper has the non-linear finite elementary analysis of the application of the double-row pile in the foundation pit support,has the comprehensive consideration on the excavation boundary conditions for the foundation pit,the changes of parameters in the excavation stage construction,and the stressed characteristics of the double-row pile,and analyzes the stress of the foundation pit and the double-row pile from the calculation results,so as to conclude that the application of the finite elementary analysis method and the double-row pile in the foundation pit can have better effect.
