Research on stability of excavation support of working well under complex geological conditions based on FLAC3D
Working well excavation depth is large,diameter is wide,accompanied by soil support problems.Taking the actual process as an example,this paper analyzes the stability of a working well with a depth of 8m and a diameter of 7.5m during excavation.Numerical simula-tion software FLAC3D was used to simulate the excavation process,and the horizontal displacement of the working pit top,the horizontal dis-placement of the concrete wall along the buried depth of the working well and the soil resistance around the wall were analyzed.Based on the analysis results,engineering suggestions were given to provide reference for similar projects.
