吉音水利枢纽面板堆石坝趾板设计

Toe Slab Design for Face Rockfill Dam of Jiyin Water Control Project

吉音混凝土面板堆石坝地处新疆山区,本文介绍了吉音面板堆石坝的趾板结构设计,根据坝址处的地形、地质条件,对左、右岸及现代河床段趾板分别采用了不同的设计方案,以满足工程安全和经济的要求;同时针对新疆地区冬季气候严寒的特点,采用沉埋式止水方案,确保冬季水位变动区止水设施的安全。

Jiyin concrete faced rockfill dam is located in mountainous area of Xinjiang.In this paper,the author introduces the design of toe slab structure of Jiyin concrete faced rockfill dam.Based on the conditions in topography and geology at dam site,different designs are adopted for toe slabs of left bank,right bank,and relative river bed,to meet the demand for safety and economics.Also in view of local cold characteristic in winter,a submerged water stop scheme is adopted to ensure the safety of water stop facilities be put in water level variation area in winter.
