Research on the Optimization of Dam Foundation Seepage Control System

Abstract:

The starting time of Dragonite hydropower station in Dadu River Sichuan delayed, which led to the depth of the cofferdam cut-off wall reduced in actual construction. In order to adapt to this situation, it’s necessary to optimize the processing scheme of sand layer dam foundation which is put forward in the feasibility study stage. Combined with the characteristics of engineering, considering to reduce or cancel the curtain grouting in coarse grain granite foundation of riverbed on the right bank in the feasibility stage design, this paper is aimed to study on the optimization design of Dragonite hydropower station dam foundation. The paper has not only a great guiding significance in engineering construction process, but also gives references to the similar earth-rock dam project for treatment of sand layer dam foundation and the arrangement of dam foundation seepage control system.
