摘　　要：岩质高边坡一般地质条件复杂,面广坡高,其影响因素非常复杂。为研究长河坝水电站泄洪洞进口边坡的稳定问题,对该边坡进行数值计算,并进行表观变形、多点位移及锚索荷载等监测。结合边坡的多种监测成果,对边坡的表面和深部变形进行了分析,以此确定边坡的稳定性。从监测成果来看,边坡的整体变形量级适中或偏小,锚索荷载以适度松弛为主,且应力与变形已趋于收敛。理论与实际监测结果表明,该边坡稳定性良好,其成功经验可以供其他类似工程借鉴。Generally, high rock slopes have characteristics like complex geologic conditions, large areas and considerable heights. In order to study the slope stability of Changheba Hydropower Station, a numerical calculation of the slope stability is conducted and the measured surface displacement observation, the multi-point displacement meter and the load of anchors are used in the slope analysis. Combining a variety of monitoring results of the slope, both the surface and deep deformation are analyzed to confirm the stability of the slope. From the monitoring results, the overall deformation magnitude of the slope is small or moderate, and the anchor load is mainly moderate relaxation and the stress and deformation have been convergent. The theory and the actual monitoring results show that the slope is stable. The results are of use and serve as a reference for similar engineering projects.
