在围岩质量较差时，渗流效应对圆形洞室径向应力的影响比围岩质量较好时的影响大。
The influence of seepage effect on radial stress around circular opening is more significant in poor quality rock mass than in good quality rock mass.
对于深埋圆形洞室地基可视为一个双向受压无限板孔应力集中问题，由此也得到其弹性理论解析解。
For deep burying cavern foundation, it is treated as a problem of infinite plate containing a hole, whose analytical solution can be obtained by using elasticity theory.
然后给出30组以圆形为均值的随机数据，并以此为例对不规则边界洞室及夹塞区进行了一些初步研究。
Then, we gives 30 sets of random data whose average shape is circularity. Some pilot studies of arbitrary shape cavity and inclusion are done according to the data.
