The deformation of mountains induced by reservoirs around high arch dams may influence the safety of those arch dams, but the underlying mechanisms of this phenomenon have not yet been elucidated. The abutment movements of the Jinping-I and Xiluodu arch dams during reservoir impoundment are analyzed systematically in this paper, and the analysis reveals that impoundment led to basin irreversible uplifts. The underlying mechanisms are analyzed from the viewpoint of the constitutive relation of rock mechanics. Based on the theories of poroelasticity and poroplasticity, the effective stress principle of rock is deduced considering the effect of high pore pressure. The modified nonlinear finite element program TFINE is used to simulate the abutment movements of the Jinping-I arch dam, and the calculated values are in accordance with the measured values, verifying the validity of the revised effective stress principle.

水库蓄水引起的高拱坝坝肩运动分析

高拱坝周围水库引起的山体变形可能会影响高拱坝的安全，但这种现象的潜在机制尚未阐明。系统分析了锦屏一级和溪洛渡拱坝在蓄水过程中的坝肩运动，分析表明蓄水导致盆地不可逆隆升。从岩石力学本构关系的角度分析了其潜在机制。基于孔隙弹性和孔隙塑性理论，推导了考虑高孔隙压力影响的岩石有效应力原理。采用修正的非线性有限元程序TFINE模拟锦屏Ⅰ号拱坝的坝肩运动，
