| 中文摘要: |
| 该文阐述了通过对太湖水库溢洪道进行模型试验，复核原设计方案的合理性，并提出优化设计方案.由模型试验结果可知溢洪道泄流能力满足设计要求，但鼻坎挑流挑距过短，水舌空中消能不充分，冲坑尺寸大，对下游产生严重冲刷.通过对挑流鼻坎挑角、反弧半径等体型优化设计，挑流形态明显改善，坝体及岸坡稳定不受影响，说明设计合理，对类似工程有一定借鉴意义. |
| 英文摘要: |
| This paper expounds the model test of the spillway of Taihu reservoir，reviews the rationality of the original design scheme，and puts forward the optimization design scheme.The results of the model test can be seen that the spillway spillcapacity meets the design requirements，but the nasal pickling distance is too short，the water tongue air energy dissipation is not sufficient， the size of the punch is large， and the downstream is seriously washed.By increasing the size optimization of angle dingling and anti-arc radius，the pattern of pick-up is obviously improved，and the stability of dam body and shore slope will not be affected，indicating that the design is reasonable and has some guiding significance for similar projects. |
