摘要
螺滩滩群位于广西融江浮石与大浦枢纽之间的水位不衔接段,该段河道水浅流急,碍航严重,急需整治。应用新开发的平面二维有限单元水流数学模型,针对螺滩河段的具体碍航特性,提出了相应的整治措施,并对不同的整治方案进行了优化分析。最后,给出了满足规划设计要求的航道整治方案。
The group of Luo beach is located in the Rong River between Fushi Pivot and Dapu Pivot, in which the water level is not continuous and the channel is bend, shallow and rapid in natural state. The regulation works are strongly required because of obstructing navigation. A 2-dimensional flow numerical model is presented, which is applied to simulate the navigation channel regulation schemes according to the detailed characteristics of obstructing navigation in Luo Beach section. And the optimistic analysis for various regulation schemes is performed. At last, the reasonable regulation schemes are presented.
