| Abstract: | Suofengying Hydropower Station is located in a karst region with complicated engineering geological and hydrogeological condition, for which the dam is a RCC one with the height of 115.80 m. The design dam foundation surface is on the center of a weak weathered zone. Under this condition the consolidation grouting is adopted locally to the weak zone to heighten the bearing capacity; the anti-seepage grouting curtain is made with the mixing grout of both the cement and the fly ash and then the intactness of the foundation rock and the grouting effect are tested with the geophysical exploration as well. All of these measures are the useful trials for the foundation treatment for the dams to be constructed within the karst regions. |
