浅谈斜卡首部面板堆石坝坝基厚层粉土质砂层开挖OA
Excavation of thick layer of silty sand in foundation of the head of the Xieka Concrecte Rockfill Dam
在水利水电工程水库大坝常遇到复杂基础需进行处理.斜卡水电站面板堆石坝坝基为承载能力低、饱水时呈流态的堰塞沉积的粉土质砂层,本文通过总结大面积、大厚度条件下粉土质砂层的开挖方法,为类似基坑开挖工程方案制定提供借鉴经验.
In the reservoir dam of water conservancy and hydropower engineering,the complex foundation is of-ten encountered and needs to be treated.The foundation of the panel rockfill dam of Xieka Hydropower Project is the silty sandy layer of the dam filling sedimentation with low bearing capacity and fluidity when saturated.This paper summarizes the excavation methods of large area and large thickness silty sandy layer,hoping to provide reference for similar foundation excavation projects.
