基于均匀设计法的地下硐室位移反分析

Back-Analysis of Displacement of Underground Chamber based on Uniform Design Method

基于均匀设计理论,对小湾水电工程地下硐室位移进行反分析,获得了地下厂房附近区域的材料参数和地应力大小,在此基础上,对厂房硐室的后期开挖进行了预演,预测结果与实际监测结果一致,从而证明均匀设计法在地下工程位移反分析中具有较高的实用价值和广阔的应用前景。

Based on uniform design method, through back - a- nalysis of displacement of underground chamber for Xiaowan Hy- dropower Project, the material parameters and stress field of rock near underground chamber are acquired, and the displacements of the chamber during the late excavation are pre - estimated, pre - estimated results are consistent with the real monitored resuits. It is proved that uniform design method has relatively high practical value and an extensive prospect of application in displacement back - analysis of underground engineering.
