| 摘 要： | 针对黄金坪水电站进水口边坡1570m高程以上潜在不稳定块体，在对强度折减法适用性进行验证的基础上，采用三维强度折减法进行了稳定性分析．研究结果表明：该块体三维效应明显，主要表现在侧边界的阻滑作用．在实际工程中，对于三维效应明显的边坡，可以适当考虑边坡的三维效应，从而保证支护措施的经济合理．

| Abstract: | On the premise of the applicability of strength reduction method （SRM）, the stability of potentially instable block above EL 1 570 m at intake slope of Huangjinping Hydropower Station is calculated by 3D-SRM. The calculated results indicated that the three-dimensional effect of the potentially instable block is significant, which is mainly caused by the resistance of lateral boundary. The slope with obviously three-dimensional effect, should be taken into account to ensure the rationality of support measures. |
