Description

[0002] With the rapid development of urbanization, more and more underground projects, especially foundation pit excavation, are used in the development and utilization of underground space. However, during the excavation of the foundation pit, the soil inside and outside the foundation pit and its surrounding structures may cause deformation, settlement or collapse due to changes in stress state, which may cause engineering disasters in serious cases. Therefore, during the construction of the foundation pit, the foundation pit and its surrounding strata should be fully monitored to ensure the safety of the project.
