摘　　要：复合土钉墙是一种新型的支护技术 ,不同于传统的土钉支护。本文将复合土钉墙支护技术分别应用于饱和黄土地层和粉喷桩复合地层 ,并通过有限元模拟计算 ,对其在不同地层条件和不同开挖阶段的轴力情况进行了分析研究。可以看出 ,复合土钉所受的轴力不仅随地层条件的不同而不同 ,而且随基坑开挖深度的增加而增大。Composite soil nailed wall is a newly support technology that is different from the traditional soil nailed.This paper,by using the FEM,researches the axis force of the composite soil nailed wall in different excavating phases and different loess soil areas that are full of underground water and bearing mechanic composite layer.We can draw the conclusion that axis force of the composite soil nailed wall is different in different condition and different excavating phases,which gave a benefit reference on more research.
