摘要
采取高趾墙作为非受力结构的垂直防渗体,在狭窄河谷吉音混凝土面板堆石坝的设计中与趾板、面板共同构成坝体上游封闭防渗体系的设计思路,并进行高趾墙三维静、动力有限元分析。结果表明,高趾墙在各种设计工况下均能满足设计要求。作为一种新型的防渗结构,高趾墙防渗体可为面板坝在应对不利地形、地质问题时提供一个新的设计思路。
The design of upstream impervious system for Jiyin CFRD in a narrow river is conducted with a new idea of taking the high toe wall as a non-stress vertical impervious structure and constituting the system with toe slab and face slab together. The three-dimensional static and dynamic finite element analyses for high toe wall are also conducted herein. The results show that the high toe wall can meet the design requirements in all design conditions. As an impervious structure, the high toe wall provides a new idea for CFR/） design to deal with the issues of poor topographical and geological conditions.
