The maximum excavation depth of a deep foundation pit project reaches 24.2m,and the support scheme is underground continuous wall+Len steel plate pile+internal support.The engineering quality of the foundation pit support system has a significant impact on the stability of the structure.In the research process,the envelope level displacement,surface settlement and level support axial force are used as quality monitoring indicators.The sensor and automatic acquisition device are used to obtain the monitoring data,and the alarm value is set.Once the safety threshold is exceeded,the information system will issue an early warning signal.From the excavation of the foundation pit to the construction of the main structure,the whole process of the quality of the foundation pit support system is monitored to ensure the safety of the operation.
