| 摘要: |
| 通过水力学模型试验,对偏心铰弧门突扩跌坎体型的水流流态、空腔特性及其对掺气量、侧墙压力分布和水下噪声等的影响进行了观测,对突扩跌坎体型水力及空化特性进行了研究,确定突扩宽度Δb=0.8 m,并以突体高度低于4mm作为施工不平整度的控制标准。 |

| Abstract: |
| Considering social,eco-environmental and economic factors,the projects-index system of cascade reservoirs compensation benefit of the Yellow River mainstream is established,and with AHP and catastrophe evaluation,synthetically evaluation was done of the six schemes of cascade reservoirs compensation benefit of the Yellow River mainstream.Results show AHP and catastrophe evaluation methods can be used in Multiple Criteria Decision-making (MCDM). |
| Key words: discharge tunnel sudden enlargement and bottom drop types hydraulic characteristic model test |
