摘　　要：本文以某地下水封洞库工程为依托,基于监控量测数据,利用图表分析法,分析下洞库围岩变形并评价稳定性。经研究得出,多点位移计监测围岩内部位移曲线随开挖断面由近到远的变化形式,从而得出围岩变形达到稳定的几个阶段。围岩表层收敛监测的位移-时间曲线的变化主要经历“急剧增长-缓慢增长-收敛稳定”3个阶段。研究成果可为该地下水封洞库工程施工方案优化和最佳支护时机提供数据支撑,为后续类似工程项目的设计与施工提供参考依据。Using a groundwater-sealed cave storage project as basis,this paper analyzed the deformation and stability of the surrounding rock of the lower cave storage through the chart analysis method,based on monitoring and measurement data.Findings indicate that the internal displacement curve of the surrounding rock can be effectively analyzed by a multi-point displacement meter,which provides measurements of the defbnnation at different sections of the excavation from near to far.As a result,several stages of deformation can be identified when the surrounding rock approaches stability.In addition,our convergence monitoring of the surrounding rock surface revealed a deformation curve that showed three main stages:"rapid growth—slow growth—convergence and stability."Overall,these research results can be utilized to support data-driven decisions for the optimization of the construction plan and the timing of underground water-sealed cavern projects.Moreover,they can be a useful reference for future design and construction of similar projects.
