| Abstract: | The foundation of major hydraulic structures of Gezhouba project,such as the dam,powerhouse etc.,is the red rock bed of lower Cretaceous system. The foundation rock characterizes as low strength, well stratified, bad hydrophysical features and complicated geological condition. Several key technical issues are discussed in this paper, such as the necessity and feasibility of consolidation grouting for foundation rock, feasibility of seepage prevention grouting and judgement criteria for grouting, seepage stability and protection for soft interbedded layer etc. According to the observation data of dam foundation, the foundation consolidation and seepage control measures of the red rock bed and seepage stability and protection effect of soft interbedded layer are analysed and evaluated. |
