拱坝坝顶溢流的下游消能防冲措施 ,一般根据各工程实际情况 ,或护固岸坡 ,或设置二道坝形成水垫消能 ,以确保大坝安全。通过对洪溪一级水电站拱坝溢流消能防冲问题进行试验研究 ,根据工程实际情况 ,提出安全、可行、经济的泄洪布置方案
The downstream energy dissipation and erosion prevention measures of arch dam crest relief generally depend on the actual conditions of each project or protect the bank slope or set up water dam dissipation of Erda dam to ensure dam safety. Through the experimental research on overflowing energy dissipation and anti-scouring of the arch dam in Hongxi First-cascade Hydropower Station, a safe, feasible and economical arrangement of flood discharge is proposed according to the actual situation of the project
