清华洞水库岩溶地质条件及防渗体系
Karst geological conditions and seepage control system of Qinghuadong Reservoir
摘要
Abstract
For controlling serious karst leakage of Qinghuadong Resevoir,the leakage sections were identified. According to the engineering geological conditions of the dam site, the position and seepage line of the plugging holes body were selected by adopting seepage control project with small amount of work and avoiding well developed karst caves. According to the the hub area karst development law, characteristics and hydrogeological conditions and the distribution of relatively impermeable layer, we adopted curtain grouting corridors of the upper and lower levels. The maximum depth of the formed seepage curtain is 145m, and the maximum width is 558mm. The average permeable rock rate fell from 13.38Lu to 1.25Lu, the seepage effect is remarkable, and the reservoir has been properly build operation.关键词
