SEEPAGE CHARACTERISTICS OF FOUNDATION OF DANJIANGKOU DAM

摘要

Magmatic rocks, metamorphic rocks and sedimentary rocks are distributed over the Danjiangkou dam foundation. Seepage characteristics of these rocks, especially the seepage characteristics of the fault fracture zone in the magmatic rocks and the seepage deformation characteristics of the red layer in the sedimentary rocks and the weak interlayer in the metamorphic rocks should be identified. Technically feasible and economically reasonable seepage control measures were designed according to the related seepage control technologies and corresponding geological conditions.
