摘要
对一典型的反倾向层状结构岩质高边坡进行了非线性三维数值模拟。数值模型中同时模拟了依存于高边坡的一个进水口大坝和坝下的4个引水隧洞,并且考虑了高边坡的复杂地质条件、支护措施和开挖工况。运用此数值模型研究了开挖卸荷、大坝生成以及水库蓄水对高边坡的应力、变形状况和稳定性的影响。研究结果为工程建设提供了有意义的参考。
3D numerical simulation with nonlinear large-deformation is conducted for a high rock slope engineering with typical antidip laminate structure. A intake dam attached to high slope and four intake tunnels under the dam are simulated simultaneously, and the complicated geological factors, support measures and excavation conditions of the slope are also taken into account. The influence of excavation unloading, dam generating and reservoir filling on the deformation and stress distribution of the slope is studied with numerical model.
