深基坑施工过程的三维数值分析

Three-Dimensional numerical Analysis of Deep foundation Pit excavation

通过一个工程实例,采用Plaxis 8.0软件对基坑开挖过程进行了三维数值分析,得到了边坡土体的水平位移和坡顶地表沉降值的分布规律。将数值计算结果与实测值进行了比较,二者基本吻合。研究表明,Plaxis 8.0软件用于基坑开挖与支护的数值模拟是可行的,能够为工程设计与施工提供正确参考。

Using the software Plaxis 8.0, the three - dimensional excavation of deep foundation pit were analyzed through a case. The distributions of horizontal displacement of slope and settlement of ground were obtained. The horizontal displacement and settlement obtained by the simulations agree well with those measured data. The results indicate that the software Plaxis 8.0 was feasible in the process of the numerical simulation of foundation pit excavation and support, and the computed results can provide references for the design and construction of practical engineering.
