摘要
洞室的围岩压力与洞室的形状、大小是有密切关系的 ,运用有限元法的基本原理 ,采用ANSYS软件对圆形、矩形和拱形洞室的围岩应力状态进行了数值模拟分析。并将其分析结果与规范规定及传统方法的简化公式求得的结果作了比较 ,得出了一些有益的结论 。
The pressure of surrounding rock of the tun nel is closely related to the shape and size of the tunnel, in this paper the stress of surrounding rock i n circular, rectangular and arched tunnels is numerically simulated by ANSYS sof tware on basis of fundamental principles of FEM. The results obtained are compar ed with those required by the codes and obtained by the simplified equation of t raditional method, some conclusions have been drawn and the problems encountered in practice are pointed out.
