ABSTRACT
Taking an actual foundation pit project as the research object, this study detects the displacement of the diaphragm wall, and analyzes the displacement of the diaphragm wall. The research results show that the internal support of the diaphragm wall can effectively reduce the horizontal displacement of the diaphragm wall, which is more conducive to restraining the horizontal sliding of the soil behind the wall and ensure the stability of the diaphragm wall. With the increase of excavation depth, the maximum horizontal displacement of diaphragm wall to the inner side generally increases gradually. With the continuous progress of the excavation process, the horizontal displacement of the top of the diaphragm wall first moves to the inside of the foundation pit and then to the back of the wall, and the diaphragm wall moves down gradually along the displacement 0 point within the depth range. The results show that the horizontal displacement of the diaphragm wall remains at a safe and stable level.
