摘要
董箐水电站面板堆石坝主要堆石料采用砂泥岩料，存在渗流控制和变形控制等技术问题，通过对砂泥岩料试验研究和坝体分区方案比选，提出了适应砂泥岩特性的分区设计，达到了加快施工进度，节约工程投资，保障工程安全的目的。
The main roekfill materials used in the CFRD of Dongqing hydropower project are sand and mudstone. Technological problems such as seepage control and distortion control do exist. Through test and research of the sand and mudstone materials, and comparison and selection of the dam blocking alternative, the blocking design is proposed to adapt to the characteristics of sand and mudstone, which achieves the goal of speeding up the construction schedule, saving the project investment and protecting the engineering safety.
