摘　　要：天生桥二级水电站首都枢纽的防沙工程充分利用天然河弯环流、人工环流及沉沙排沙等措施， 采用多级水位调度方式， 控制溯源冲刷，The inlet of the Tianshengqiao Second Cascade Hydropower Station is located at a river bend. To prevent sediment particles from entering the canal of the power station comprehensive measures including utilization of circulation flow in river bend, construction of submerged guide dike to form an artificial circulation, establish of settling basin as well as the operation scheme to reasonably control the water level are adopted. The measures are effective in prevent from the entering of coarse sand and reducing the wearing of the turbines.
