地下水封储油洞库施工安全监测及稳定性分析

Construction Safety Monitoring and Stability Analysis of Underground Water-sealed Oil Storage Caverns

以某大型地下水封储油洞库为依托,对其储油洞室施工阶段的洞周变形、围岩内部位移、锚杆应力、松动圈等监测数据进行了统计分析,得出了监测数据的变化范围和变化规律,并分析了洞室稳定性,验证了各监测技术在大型地下洞库的适用性。

Based on a large underground water-sealed oil storage cavern in China,the monitoring data of surrounding rock convergence,internal displacement,anchor bar stress and surrounding rock loosening circle in the construction stage of oil storage cavern are statistically analyzed,the change range and law of monitoring data are obtained,the stability of the cavern is analyzed,and the applicability of each monitoring technology in large underground cavern is verified.
