摘要
基于柱状节理玄武岩围岩应力应变及变形等监测成果,系统地进行了围岩松弛变形演化规律和变形机制研究,初步建立了能量速率和单位变形力双重指标的围岩安全评价体系,研究成果表明:开挖有利于释放围岩浅层节理变形所产生的能量,及时支护有利于控制围岩变形所伴生的隐节理变形所产生的能量。
Based on the monitoring results of columnar jointed basalt rock stress and strain deformation,the research systematic studied the evolution of rock loosening deformation and deformation mechanism,initially established a surrounding rock safety evaluation system with energy rate and unit deformation force double indexes. The research shows that： excavation is conducive to release the energy that generated by shallow surrounding rock joints deformation,timely support can help control energy generated by hidden joints deformation which produced by surrounding rock deformation.
