| 摘 要： | 亭子口水利枢纽采用三期导流方案,二期基坑施工期间由导流明渠过流。由于导流明渠底宽受到限制,使设计单宽流量增大,明渠出口消力池消能效果差,出口流速大,且坝址岩层为近水平向构造,岩石裂隙发育,整体性差,下游冲刷严重。通过分析研究,采用下游天然河道消能,对明渠出口进行适当的防冲保护,能确保明渠运行安全。现导流明渠工程已建成通水,并经过了2010年汛期洪水的考验,运行情况良好。

| Abstract: | We adopt the third phase diversion scheme in Tingzikou Hydropower Station,while the diversion channel applied during the foundation pit construction in the second phase.Because of the limited bottom width of diversion channel,the designed unit width discharge is large,and the effect of energy dissipation in the stilling pond at the outlet of open channel is poor with a large exit velocity,meanwhile,the rock stratum of dam site is nearly horizontal rock structure with the developed rock fissures,therefore,wi... |
