摘要
层状复合围岩岩体软硬相间，不满足均匀、连续及各向同性的要求．研究依据多种测试手段，对开挖后围岩的稳定性和变形进行实时监测．并对数值模型进行三维非线性弹塑性计算、分析，比较准确地预测了围岩的动态变化过程，研究了层状围岩位移和应力的变化规律。
The layer composite rockmass is soft and hard alternately, and does not meet the conditions of homogeneity and isotropy. The stability and deformation of roekmasses near to the walls of houses are determined by using several measurements during the arch part excavation process, and the numerical model of underground houses in stratihed anisotropical rocks is analyzed using three dimensional nonlinear element model. The changing law of displacement of ayer composite rockmass is studied for first time.
