摘要
本研究以某实际基坑工程为研究对象,对连续墙的位移进行监测,并对连续墙的数据进行分析。研究结果表明:地下连续墙的内部支撑可以有效减少地下连续墙的水平位移,且更有利于抑制墙后土体的水平滑动,保证地下连续墙的整体稳定性;随着开挖深度的增加,地下连续墙向内侧的最大水平位移一般逐渐增加;随着开挖过程的不断推进,地下连续墙顶部的水平位移首先向基坑内侧移动,然后向墙后移动,地下连续墙在深度范围内沿位移0点逐渐下移,地下连续墙的水平位移保持在安全稳定水平。
This study takes an actual foundation pit project as the research object, and monitors the displacement of the diaphragm wall and analyses the data of the diaphragm wall. The research results show that the internal support of the underground diaphragm wall can effectively reduce the horizontal displacement of the underground diaphragm wall, and is more conducive to inhibiting the horizontal sliding of the soil behind the wall and ensuring the overall stability of the underground diaphragm wall;with the increase of the excavation depth,the maximum horizontal displacement of the underground diaphragm wall to the inner side generally increases gradually. As the excavation process continues to advance, the horizontal displacement at the top of the diaphragm wall first moves towards the inner side of the pit and then towards the back of the wall, with the diaphragm wall gradually moving down along the displacement 0 point within the depth range, the horizontal displacement of the underground diaphragm wall is maintained at a safe and stable level.
