|
摘要
针对混凝土高拱坝抗震安全评价中存在的研究不平衡的问题,本文从坝址的地震动输入、坝体结构体系的地震响应、大坝混凝土的动态特性及破坏机理三个方面进行了总结。针对目前存在的问题提出几点建议,并指出今后混凝土高拱坝抗震安全评价研究的方向和重点。
In view of the unbalanced research in seismic safety evaluation of high arch dam,this paper summarizes from three aspects : seismic motion input at dam site,seismic response of dam structure system,dynamic properties and failure mechanism of dam concrete. Then suggestions on existing problems were made and the research directions and emphasis of seismic safety evaluation of high arch dam in the future were put forward.
