摘要
为了论证和优化拟建汉江雅口航运枢纽总体布置,在初步设计阶段采用比尺为1∶100的整体定床正态物理模型,对枢纽泄流能力进行试验研究。文中阐述了设计方案工程布置条件下的枢纽泄流能力、分析了枢纽泄流方面存在的问题及其影响因素,针对设计方案在泄流能力方面存在的不足,通过调整枢纽上游隔流建筑物布置形式、缩窄船闸导航墙宽度及河床局部疏浚等多种优化工程措施,提出了满足枢纽泄流能力的总体布置方案,研究成果可供类似工程参考和借鉴。
Based on the integrated physical model test with the scale of 1：100 in preliminary design phase, we studied the discharge capacity of Yakou hydro-junction in Hanjiang River in order to demonstrate and optimize the general planning project. In this paper, we described the discharge capacity of hydro-junction under the engineering arrangement in design scheme, and analyzed the existing problems and its influence factors. Aiming at the disadvantages of discharge capacity which exist in the design scheme, we proposed the optimized measures such as adjustment of layout pattern of separation levee at the upstream of the hydro-junction, narrowing the width of ship lock guide wall and the local dredging in the channel bed. The research results may serve as reference for the other similar projects.
