深浅交替地下连续墙的变形研究

The Deformation Character Analysis of Diaphragm Wall with Deep Panels Alternate Shallow Panels

深浅交替地下连续墙作为一种新的地下连续墙形式,其应用较其他形式的地下连续墙更为广泛,研究其在基坑工程中的变形规律具有重要意义。通过对某基坑工程中深浅交替地下连续墙的变形性状进行监测,将不同深度处的水平位移以及地下连续墙墙顶沉降量与时间关系进行分析,采用模拟软件进行支护计算,得到各个开挖工况下深浅交替地下连续墙墙体竖向和水平位移的变形规律。

As a new type of underground diaphragm wall, underground diaphragm wall with alternate depth and shade is widely used, which is different from other kinds of underground concrete wall. It is of great significance to study its deforma- tion regularity in foundation pit engineering. Through the monitoring of the deformation of underground diaphragm wall with alternate depth and shade for a foundation pit engineering, the horizontal displacement at different depths and the relationship between the settlement of the top of underground diaphragm wall and time will be analyzed. Base on this, the simulation soft- ware is used to do the Supporting Structure calculation to obtain the deformation regularity of vertical and horizontal displacement of underground diaphragm wall under different excavation conditions.
