一种水利工程的基坑监测预警系统
By generating theoretical and actual response sequences and combining information on horizontal distance, depth, permeability, and water-stop curtain, abnormal pore pressure response sequences in foundation pits are identified. This solves the problem of difficulty in locating hidden seepage risks in existing technologies, enabling early identification and zonal positioning, and improving the reliability of safety monitoring of foundation pits in water conservancy projects.

AI Technical Summary
Existing methods for monitoring and warning the safety of foundation pits are insufficient to identify the spatial propagation sequence of pore water pressure changes after the activation of dewatering wells or the adjustment of pumping intensity. This makes it difficult to locate hidden weak points in water-stopping or local water-permeable channels in a timely manner, especially in water-rich strata where abnormal propagation phenomena exist.
By acquiring the theoretical and actual response sequences of multiple pore pressure monitoring points, and utilizing information on horizontal distance, burial depth, soil permeability, and cutoff wall barrier, a theoretical response score is generated. Combined with the actual response start time, abnormal pore pressure response sequence zones are identified, providing early warning and locating hidden seepage anomalies.
It improves the targeting and reliability of foundation pit safety monitoring, enabling early identification of abnormal propagation patterns such as early response from distant points, early response from lower layers, and early response from one side, providing a basis for zoning and positioning, reducing the uncertainty of human experience judgment, and improving the reliability of early warning results.
