桩锚支护结构在深基坑工程中的应用

The application of pile-anchor joint supporting structure in deep excavation works

利用基于显式三维快速拉格朗日算法的FLAC3D程序,结合某基坑开挖支护工程实例,对基坑边坡土体的变形进行了分析,并对桩顶的位移,受力与锚杆的受力进行了初步探讨。

Utilizing FLAC3D program of explicit rapid three-dimensional lagrange algorithm and combining supporting engineering of one deep excavation works the deformation of side slope soil of this foundation pit is analyzed. The displacement of pile cap, force and mechanical behaviors of anchor rod are primarily discussed.
