混凝土重力坝关键部件的毁伤判据分析

Analysis of Damage Criteria for Key Components of Concrete Gravity Dams

为了解决在爆炸载荷作用下混凝土重力坝关键部件功能毁伤分析和毁伤判据取值缺乏的问题,基于结构树和毁伤标准,分类梳理了混凝土重力坝的关键部件,并从毁伤模式分析、毁伤规律归纳、毁伤判据研究和毁伤结果判定4个方面开展关键部件的毁伤分析,将混凝土重力坝的物理毁伤和功能毁伤关联起来。结合毁伤标准,建立了一套混凝土重力坝关键部件的毁伤等级判定方法,给出了定量判定方法和准则。

To analyze the function damage of key components of concrete gravity dams and explore the damage threshold of them under blast load,key components of the concrete gravity dam were classified based on the structure tree and the damage standard firstly.Subsequently,the damage analysis of key components was carried out from aspects of damage mode analysis,damage law induction,damage criterion research and damage result determination.Furthermore,the physical damage and functional damage of the concrete gravity dam were related.Thereby,a damage level criteria for key components of concrete gravity dams was proposed with the damage standard.Moreover,the judgment method and judging criteria were given.
