摘要
对复杂变化地质环境下的主厂房围岩进行了各种因素作用下的综合稳定分析,并依据多种测试手段,对开挖后围岩的稳定性和变形进行实时监测,掌握了洞室层状围岩变形破坏特征。研究了围岩的动态力学特征和变形规律,得出了有益的结论,对施工开挖方案的优化具有重要参考价值。
The comprehensive stability of the rockmass influenced by various factors in complex geological environment is analyzed. The stability and deformation of surrounding rockmass are monitored on-line using several measurements. The destroyed characteristics of layer composite rockmass deformation are obtained. The dynamic mechanical properties and distorted rules of the surrounding rockmass are analyzed and some good conclusions are given. The results provide a reliable basis for project construction.
