| 摘要: |
| 富流滩船闸改扩建工程是渠江广安航运建设工程的重要组成部分,对促进川东地区经济社会发展具有重要意义.由于新建船闸等级及综合水力指标较高,因此,需对其进行水力学模型试验以优化输水系统设计.根据初步设计的富流滩船闸输水系统,通过1∶25的整体物理模型试验对其输水水力特性进行详细研究.试验结果表明:富流滩船闸采用闸底长廊道侧支孔明沟消能的输水系统布置是合理的,推荐的阀门开启方式下各输水水力特征均满足设计和规范要求. |

| Abstract: |
| The reconstruction and extension project of Fuliutan shiplock is a main part of the navigation construction project of the Qujiang River in Guang’an City,which is quite significant to the economic and social development of the east Sichuang Province.Due to the high standards of the new lock,a model test should be carried out for the optimal design of the filling and emptying system.Based on the preliminary design of the filling and emptying system,a 1∶25 physical model has been set up for studying its characteristics.The results indicate that the overall layout and the design of the bottom longitudinal culvert system with side ports and open ditches are reasonable,and the hydraulic characteristics under recommended valve opening mode have all satisfied the requirements of the design and related codes. |
