摘要

通过东深供水改造工程凤岗隧洞段的岩体参数反分析，探讨了在计算中采用对屈服单元进行弱化来模拟开挖引起的松动与破坏范围的新方法，所得结果与实测值相吻合。

Abstract

The back analysis of displacements for Fenggong Tunnel of the East River-Shenzhen Water Supply Reconstructing Project is carried out. A new method of using the soften yielded elements in the finite element method simulating the fractured and flexible range by the excavation is discussed. The analysis results of the tunnel by this new mothod are consistent with the measured values.
