摘要
在分析洞庭湖双向水流浅滩演变特点的基础上,提出了双向水流河段浅滩整治的原则,并应用到洞庭湖区白沙至茅草街河段航道整治中。研究表明,综合考虑顺流、逆流水流流态,选择对冲刷最为有利的航槽,采取疏浚和修建整治建筑物相结合的方法,集中汛末水量冲刷主航槽,辅以疏浚挖槽,增加枯期水深,能够取得良好的工程整治效果。
Based on the analysis of the evolution characteristic of shoal with bidirectional flow in the Dongting Lake, the regulating principles are put forward and applied to the channel renovation of the reach from Baisha to Maocaojie in the Dongting Lake. It is demonstrated that considering fair flow and reverse flow synthetically, choosing the optimum channel to scouring, adopting the method of combining dredging with building regulating structures, concentrating the water flow at the end of flood period to scour the main navigation channel, excavating the channel during drought period, good renovation effects can be obtained.
