摘要
本文对圆形洞室受到自重作用时，围岩内的应力和位移进行了弹性力学和边界元分析。由算例所得结果说明两种方法相当一致。这为边界元解有较高精度这一结论提供了佐证。
In this paper,the stresses and displacements of a tunnel are analyzed by elasticity and boundary element method when it is bearing the surrounding rockmass weight.The results of two methods for an example are quite close.The conclusion shows that the calculation of boundary element method is good in precision.
