摘要
研究表明,地质条件复杂的工程边坡变形破坏模式往往表现为组合特征,为准确分析边坡的稳定性,充分的工程地质调查和变形机制研究是关键。文章通过在金沙江鲁地拉水电站上、下坝址比选设计过程中,针对下坝址左坝肩边坡综合分析了边坡的工程地质条件、岩体结构特征及变形特征,研究、预测了边坡变形破坏机制和模式,提出了加固处理措施建议,为坝址的比选提供了充分的依据。
Study shows that the deformation failure modes of slopes of projects with complicated geological conditions feature normally combination. Sufficient geological investigation and study on deformation mechanism are the key factors to accurately analyze slope stabili- ty. In this paper, the engineering geological conditions and structural ＆ deformation features of rock mass of slopes are comprehensively are analyzed, slope deformation failure mechanism and modes are studied and forecast, measures for reinforcement and treatment of slopes are provided, and sufficient supports for comparison and selection of dam sites are raised in design of comparison and selection of both upstream and downstream dam sites of Ludila Hydropower Project on the Jinsha River aiming at slopes in left abutment of the downstream dam site.
