| 摘 要： | 在不同频率流量和阻水条件下,采用一维明渠非恒定流网河数学模型,分析规划中的佛山市桥梁群对区间河道洪季行洪、枯季水环境的影响,计算洪季不同频率洪峰流量下规划桥梁群对区间河道行洪洪水位、分流比的影响,枯季时规划桥梁群对区间河道过流量、分流比的影响,进而提出规划桥梁群建设的合理化建议和限制条件,避免和有效应对规划桥梁群建设对河道的综合利用可能带来的不利影响。 |

| Abstract: | What this program was studying mainly was that under different frequency rate of flow and hinderance voyage degree condition,program bridges were for flood or low water course the influence of flood and withered season water environment,mathematics model,a dimension opening non-constant flow net river mathematics model was used to calculate the different frequency rate of flow of flood peak plan bridge crowd is all right for interval river course flood position,assign redundant civil servants to other jobs than affect,withered season program bridges for the interval inflow-rate of water turbine of river course,assign redundant civil servants to other jobs than affect,and then make restricted condition and the rational suggestion of program bridges construction,avoid and have effect build for program bridges for river course synthesize using possibility bring affection unsuccessful. |
