有限元数值模拟技术应用于基坑降水设计和结构防浮分析

Utilization of the finite element numerical simulation to design foundation pit dewater and to analyze the construction anti-float

利用有限元数值模拟技术进行建筑基坑开挖工程降水设计,在首都机场新航站楼工程中,用此项技术进行基坑降水和结构防浮分析,取得良好了效果。与传统的设计方法相比,该技术具有能适应复杂含水地层,满足不同开挖深度的基坑降水设计,具有全面模拟整个降水过程的水量和水位变化的优点。

Now,people use the finite element numerical simulation technique to design foundation pit dewater. We use the technique in Beijing airport building to design the foundation pit dewater and to analyze the construction antifloat, and get the satisfied result. This technique is different from traditional method. It has more obvious advantage. Numerical simulation can handle different depth foundation pit dewater, and can adapt to complicated water strata, it can also simulate the whole process of dewater.
