摘要
应用蒙特卡罗-有限元法模拟和计算浅埋隧道荷载破裂角,视围岩弹模、粘聚力、密度等参数为随机变量,根据各参数的分布函数进行随机抽样。用有限元ANSYS对每组抽样值进行模拟计算,并对破裂角计算结果进行统计分析,最后与物理模型试验结果进行对比。
Based on MC-FEM mathod, this paper deals with simulating and calculating fractural angles of shallow tunnels. The properties of soil is considered as random varies, the sample which is calculated in computer is got according to the probability distribution. By using the probability and the math statistics theory, the values of fractural angles is analysised. In the end the formula of calculating loads and the critical depth of shallow tunnels are also discussed.
