针对三峡工程永久船闸三闸首区闸室开挖诱发的岩体变形特征，提出了一种复杂岩体变形、应力及损伤状态的智能分析方法。分析过程中所涉及的岩体力学参数和本构模型利用现场监测到的位移进行智能识别，然后利用所确定的参数和模型，考虑动态施工和环境诱发岩体损伤的影响，对复杂岩体的变形、应力及损伤状态特征进行分析。结果表明，由智能计算得出的中隔墩顶面和两侧边坡直立墙的变形趋势与实测情况较吻合，而且开挖区表层附近出现较大区域的塑性区，直立墙和中隔墩的中上部出现拉应力区，直立墙底部拐角处出现压应力集中现象。
Aimed at the deformation characteristics of rock mass induced by the excavation in the lock chamber of the three sluices of the permanent ship lock of the Three Gorges Project, an intelligent analysis method of the deformation, stress and damage of the complex rock mass is proposed. The mechanical parameters and constitutive models of rock mass involved in the analysis process are identified intelligently by the displacements monitored on site. Then, the parameters and models of the rock mass are used to consider the influence of dynamic construction and environmental induced rock mass damage. Deformation, stress and damage state characteristics were analyzed. The results show that the deformation trend of the upright wall on the top of the septum pier and the side slopes on the two sides is in good agreement with the measured results. The plastic zone, the upright wall and the septal pier in the larger area near the surface of the excavation area In the upper part of the tensile stress zone, the vertical wall at the bottom corner of the compressive stress concentration phenomenon.
