基于工程实例的重力坝溃决模式和溃决路径分析
An actual case based analysis on failure modes and paths for gravity dam
【摘要】 基于典型溃坝案例,结合重力坝工作机理,总结了重力坝溃决原因,并分析与讨论了溃决模式和溃决路径。经分析,重力坝溃决的主要影响因素为洪水漫顶、基础缺陷和战争。基于溃坝统计和溃坝原因分析,提出了重力坝主要的3类溃决模式、11条溃决路径。
【Abstract】 Based on the typical cases of dam failures,the failure causations of gravity dams are summarized,and then their failure modes and paths are analyzed and discussed in accordance with the operation mechanism of them.The analysis shows that the main factors of the influences upon the failures are overtopping,foundation defects and war.On the bases of both the failure statistics and the failure analysis,three types of failure modes and eleven types of failure paths are concluded and given herein as well.
