京沪高铁桥墩加固基坑开挖安全监测与水利监管要点研究OA

In recent years,China's water infrastructure development has entered a phase of rapid growth,with increasing intersections between major water projects and high-speed railway networks.This study examines the Xinbei section of the Changzhou Xinmeng River Extension and Deepening Project traversing the Beijing-Shanghai High-Speed Railway,systematically analyzing safety monitoring technologies and key aspects of water conservancy supervision for large-scale ultra-deep unloading foundation pit construction beneath operational high-speed rail lines.The research demonstrates that adopting construction principles—including layered excavation,real-time support during excavation,symmetrical construction practices,and strict prohibition of over-excavation—combined with real-time monitoring through automated systems,can significantly reduce construction disturbances and ensure safe rail operations during construction periods.From a water conservancy project safety supervision perspective,this paper outlines the construction of monitoring systems,key supervision points,early warning mechanisms,and emergency response protocols for deep foundation pit engineering,providing replicable technical references for the safety supervision of similar railway-related water conservancy projects.
