喀麦隆曼维莱水电站黏土心墙堆石坝反滤料、过渡料和堆石料设计

Study of Material for Filter,Transition,and Rockfill Part of Memeve'ele Clay Cored Earth and Rockfill Dam in Cameroon

介绍了喀麦隆曼维莱水电站工程的概况,拦河坝河心岛坝段选用坝型为黏土心墙堆石坝,根据土料场粒径级配累积数据绘制被保护土料(黏土心墙)的粒径级配曲线,对反滤料和过渡料和堆石料进行级配设计。反滤料、过渡料和堆石料的设计是土石坝设计的一个重要环节,除应满足规范要求的滤水、排水、自身级配连续等条件外,还应结合施工设备等因素的影响,确保工程质量。

The main dam of Memve'ele Hydroelectric Project in Cameroon is selected to be a clay-cored rockfill dam.And the design of filter,transition,and rockfill part of the dam is of great importance in designing the dam.This paper briefly introduces the project,and then describes how the gradation of filter,transition,and rockfill part of the dam is designed according to the granulometric curve of materials exploited from the borrow area.
