摘要
根据地下洞室施工开挖程序和锚固施工方法 ,提出了大型地下洞室施工开挖过程动态模拟的三维有限元数值分析方法。依据岩体破坏特性和弹塑性力学耗散能原理 ,给出了施工开挖动态优化的评估指标和方法 。
A three-dimensional numerical method to analyze the construction process of underground opening is presented in this paper. According to the failure conditions of rock masses and principle of energy dissipation,a method to assess the excavating way is given. The influence of construction blast and anchorage support are imitated in the computation process.
