摘要
利用 Schwarz交替法 ,得到了任意次迭代后两任意形状洞室的围岩位移场 ,通过精度分析发现 :2 0次迭代后的位移结果精度非常高。初步探讨了两洞室位移反分析的应用 。
By using Schwarz′s alternating method, the displacement field is gained of surrounding rocks of two tunnels with arbitrary shapes after random times of iteration, and it is found that the precision of the displacement results is very high. In addition, the application of this study to back analysis of displacement is studied and the back analysed results are obtained with high precision.
