The engineering and geological problems of the cobble layer and fault under the fifth dam block ,the inappro-priately low elevation of the water inlet ,and the lack of reservoir escape facilities were found during the construction of Zuoxi Hydropower Station .Specific measures such as curtain grouting consolidation ,increasing the elevation of water in-let ,and the addition of diversion tunnels ,transportation tunnels and sediment ejection facilities were adopted respective-ly .The result indicates that by adopting these measures the safe construction of the engineering project is ensured ,as well as energy conservation and economic construction .
