简述了导流洞改建为永久泄洪洞时的不同消能方案和井式溢洪道的特点，给出了竖井与多级孔极组合式泄流消能塔的水流与振动试验实例，振动试验时模拟了塔基的力学特性，具体试验虽是针对一尾矿坝进行的，但这种结构形式和试验结果对水利工程设计也有一定参考价值．
The characteristics of different energy dissipation schemes and well spillway when the diversion tunnel is converted into a permanent flood discharge tunnel are briefly described. An example of water flow and vibration test for the combined well of the well and the multi-stage microporous discharge tower is given. The vibration test The mechanical properties of the tower foundation are simulated. Although the specific test is carried out for a tailings dam, the structure and test results have certain reference value for the design of hydraulic engineering.
