摘要
应用正交试验与数值模拟相结合的正交有限元法对浅埋大跨地下洞室的锚喷支护方案进行了数值模拟试验研究 ,评价了支护参数对洞室稳定性的影响 ,提出了以顶底板相对位移、地表沉降量及破坏区面积为评价指标时的最佳支护参数值 。
The numerical simulation experimental research was made on the shortcrete and bolt support scheme by orthogonal finite element method combining the orthogonal experiment with numerical simulation.The effect of the support parameters on the opening stability was evaluated.The best support parameter values of the relative displacement between room and floor,the subsidence of ground and the area of dustructive zone were proposed for the index evaluation,providing a theoretical guidance for the engineering design and construction.
