Excavation pit monitoring is a critical phase in the construction of excavation pit projects. It involves various observations and analyses of the geological and geotechnical characteristics of the pit, the displacement of supporting structures, and changes in the surrounding environmental conditions during excavation and underground construction. The monitoring results are promptly fed back to predict the deformation and stability development that will occur after further excavation, to assess the extent of the impact on the surrounding environment based on the predictions, and to guide design and construction, thereby achieving what is called信息化施工信息化 construction.

Definition of Foundation Pit Monitoring:

Excavation monitoring primarily includes: support structures, related natural environment, construction conditions, groundwater conditions, soil at the bottom and surrounding the excavation, surrounding buildings (structures), surrounding underground pipelines and facilities, surrounding major roads, and other objects requiring monitoring.

The Significance of Excavation Monitoring:

Theoretical research and engineering practice in deep foundation pit construction indicate that the combination of theory, experience, and monitoring is the correct approach for guiding the design and construction of deep foundation pit projects. For complex large and medium-sized projects or those with stringent environmental requirements, it is often difficult to draw on past experience or find quantitative analysis and prediction methods theoretically. This necessitates reliance on on-site monitoring during the construction process.

I. Utilize on-site monitoring to provide dynamic feedback for guiding the entire construction process, and understand the design strength of the foundation pit through monitoring data, providing a design basis for future cost reduction in engineering projects.

Two, gain timely insights into the construction environment — the impact and extent of influence on underground soil layers, underground pipelines, underground facilities, and above-ground buildings during the construction process.

Three, capable of promptly detecting and forecasting the occurrence and development of risks, acting as an ear and an eye to facilitate timely safety corrective measures.
