摘要
强度储备法抓住影响坝体稳定因素中最关键的强度指标,通过研究不同强度参数所对应的破坏区域的演变关系,分析坝体的稳定性和潜存的破坏机理,在混凝土坝和岩体结构的稳定分析中得到了普遍应用。但将强度储备法应用于土坝稳定性分析中属首次,以飞来峡水利枢纽土坝为例,采用二维有限元强度储备法对其稳定安全系数进行了计算分析,研究了边坡的失稳破坏机理,对安全性进行了评价,为运行管理提出了一些有益的参考意见。
The material strength reserve method is practical in the study of the stability and failure mechanism of earth dam by analysing the development of failure zone of different shear strength parameters of the earth mass of the dam. The stability in the concrete dam and ensemble architecture has got general application while analysing. In this paper, in combination with Feilaixia Multipurpose Project, application of this method to earth dam stability analysis is studied by plane FEM for the first time Through plane FEM, we can get the failure mechanism of earth dam and appraise to the security, for operating and managing put forward some reference suggestions。
