摘要

基于FLAC3D有限差分法,对某堆石坝坝址右岸坝前的一堆积体在不同坝址方案、不同工况下的变形以及应力和塑性区的分布进行了三维数值模拟研究。根据研究结果,建议采用上部削坡和开挖范围内浆砌石方案护坡;考虑到建坝调水工程、引水线路、坝体施工工程量及坝库区边坡稳定等问题,建议将坝体布置在中坝址。
The three-dimensional distributions of deformation,stress and plastic region of a right-bank accumulation body in front of a rock-fill dam under different dam site selection plans and working conditions are simulated by using finite difference method of FLAC3D.Based on the simulation results,it is recommended that the upper part of slope is unloaded and the masonry is used to support the slope in excavation area,and the dam is arranged in middle site after taking into account the water transfer project,water diversion route,construction quantities of dam and the stability of slopes in reservoir area.
