摘　　要：简要介绍了某水电站下坝址区左岸深部裂缝的发育分布特征 ,在此基础上 ,采用FLAC3D就深裂缝的存在对工程荷载作用下坝基岩体的变形和稳定性状况进行了初步分析和评价 ,结果表明 ,尽管左岸边坡中存在深裂缝 ,但岸坡在工程荷载作用下变形较小 ,整体稳定性仍较好。On the basis of introducing the distribution character of the deep cracks in the left bank of some hydropower station, the deformation features and slope stability under the condition of engineering loading were calculated and analyzed by FLAC 3D . The researched results have shown that the displacement magnitude is small, and the slope is stable after applying engineering loading, even though there are some deep cracks existing in left bank of dam site.

关 键 词：工程荷载 FLAC^3D 边坡稳定性 深部裂缝 水电站 坝址 变形
