大田水库碾压式土石坝坝体防渗方案设计

Scheme Design of Seepage Control for Rolled Earth-Rock Dam of Datian Reservoir

文章阐述了大田水库工程概况,从地形地质条件、交通条件、施工条件及工期分析、工程投资等角度分析比较,选定塑性混凝土心墙作为大田水库碾压式土石坝坝体防渗方案。通过工程实践表明,塑性混凝土心墙质量与防渗效果明显,同时节省了工程投资,并加快了工程施工进度。

This paper elaborates overview of Datian Reservoir and makes analysis and comparison based on topographic and geologic conditions, traffic and transportation, construction organization, project duration, and engineering investment. The scheme of plastic concrete core wall is adopted for seepage control of rolled earth-rock dam in the Datian Reservoir. The engineering practice shows that the quality of plastic concrete core wall and effect of seepage control are improved obviously to save engineering investment and accelerate construction progress.
