摘要
Abstract
With a deep foundation pit support project in Changchun City as the research backdrop,this paper analyzes the causes of the sudden deformation of the capping beam on the north side of the foundation pit and proposes reasonable treatment measures.The analysis shows that the main cause of the capping beam's sudden change is that during the excavation of the sump well at the base of the foundation pit,heavy rainfall caused the bottom of the foundation pit to be soaked by rainwater,and the rainwater seeped into the ground through cracks on the surface,resulting in a decrease in the strength of the soil layers both inside and outside the foundation pit,etc.;the secondary causes include a large amount of groundwater,problems such as the construction of anchor cables and uneven force on the piles.This study integrates the finite element numerical simulation with the actual monitoring data and conducts a comparative analysis.This study also proposes setting up four anchorages at the deformed part of the capping beam,and evaluates the treatment effect.The results show that this measure can effectively control the further deformation of the capping beam,providing reference experience for other similar foundation pit projects.关键词
