In order to ensure the safety and stability of the foundation pit, the support of the foundation pit is essential. The existing foundation pit supporting structure can only achieve basic support and soil retaining, and cannot display the safety condition of the foundation pit. If the rigidity of the foundation pit retaining structure is not enough or there is a sandwich layer, it will affect the overall stability and safety of the foundation pit, and even cause serious accidents. Therefore, it is very important to monitor the axial force of the foundation pit supporting structure and the inclination and displacement in the foundation pit. At present, manual monitoring is generally used for foundation pits, but manual foundation pit monitoring has errors and cannot directly reflect the safety condition of the foundation pit.
