| 摘 要： | 首次用卸荷非线性岩体力学理论研究了三峡工程左岸坝段开挖卸荷对节理裂隙岩体的影响，提出了在逐级确定的卸荷带中，进一步寻求破坏单元，从而再赋于相应卸荷参数的新思路．所得成果较常规算法有较大差别，但与实际监测成果较吻合．

| Abstract: | Influence of excavation unloading on joined crack rock mass of the left bank dam blocks of the Three Gorges Project is studied by using the theory of the rock mass mechanics of unloading nonlinear. The new train of thought about looking for the failed elements in unloading range is presented. Though the results is different from the conventional calculation, it is close to the monitoring data. |
