【摘要】 通过研究溪洛渡水电站左岸巨型古滑坡的地形地貌、地质结构、水文地质条件和主要物理力学指标,对古滑坡成因进行了分析。选取了4个典型断面对古滑坡变形进行监测,分析其稳定性。通过采取深层和浅层排水、压脚贴坡混凝土、框格梁加锚索固脚等工程措施,进行施工和监测,保证了古滑坡体的稳定性。更多还原

【Abstract】 Through the study made on the topographic features,geological structure,hydrogeological condition and main physico-mechanical indexes of the ancient landslide on the left bank of Xiluodu Hydropower Station,the causation of the ancient landslide is analyzed herein. Four typical sections are selected for monitoring the deformation of the landslide,so as to analyze its stability. The construction and monitoring are carried out through the engineering measures of deep and shallow-drainages,footing and sloping concrete,grid-beam with anchoring toe,etc.,and then the stability of the ancient landslide is ensured.更多还原
