Analysis of Stress Problem in Three Dimensional Branch Cavity by Infinite Elements

利用无界元分析有岔隧洞的应力问题,与有限元相比显示出很大的优越性,即数据准备工作量减少,而计算结果更精确．分析了空间有岔隧洞当岔洞截取长度及主岔洞夹角发生改变时,其应力分布变化情况．

Using infinite elements to analyse stress problem of branch cavity has demonstrated great superiority to finite elements, the work for preparing data is less, but the calculating result is more accurate. This paper analyses the stress results when the length of branch cavity is changed or the angle of main and branch cavity is varied.
