摘要
针对黄金坪水电站进水口边坡1 570m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.
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.
