【 摘 要 】

As the current geotechnical excavation process is affected by many factors, excavation will easily lead to abnormal conditions in the geotechnical excavation process. Based on this, this study used COMSOL Multiphysics finite element analysis to analyze the various factors affecting the geotechnical excavation process and set the various parameters of the project. This study studied the geotechnical excavation works in the presence of buildings and the absence of buildings. At the same time, the data were statistically analyzed and the changes of various parameters in the process of geotechnical excavation were studied on the basis of finite element simulation analysis. The research shows that COMSOL Multiphysics finite element analysis can effectively imitate the geotechnical excavation conditions and draw effective laws, which will be helpful for the effective development of follow-up projects and provide theoretical reference for subsequent related research.
