【摘要】 基于风险理论开展大坝安全性评估是一种发展趋势,其中风险源辨识是大坝风险分析的重要方面。结合高拱坝的结构特点和所处区域环境条件,对其面临的风险源集进行了分类,从自然灾害风险源、大坝构筑物及坝肩(基)稳定性影响风险源、人为原因影响风险源3个方面,阐述了高拱坝面临的主要风险源集,并根据锦屏一级高拱坝的模型试验研究成果,探讨了高拱坝的主要失效模式和失效路径,可为更详实的高拱坝风险分析提供基础支撑。更多还原

【Abstract】 In the security assessment based on risk theory of dam,the risk source identification is an important content.The risk sources for high arch dams were classified into three sets of natural disaster risk,dam abutment,foundation and structure stability risk and human factors risk after considering the structural characteristics and environmental conditions.The major dam failure patterns and paths of high arch dam are discussed by using the model test results of Jinping I Dam.The case study can provide basis for more detailed risk analysis of high arch dam.更多还原
