西江豹子头～柳沙娘滩航道整治方法研究

Study of the Channel Regulation Method for Baozitou～Liushaniang Shoal of Xijiang River

分析豹子头～柳沙娘滩的成滩原因,提出以疏浚为主、整治建筑物为辅的整治原则;在定床试验和定床加沙试验的基础上,考虑回水变动区河段的特点,提出切实可行的整治方案,整治效果良好。

The reason of forming the Baozitou-Liushaniang Shoal is analyzed and the regulation principle that 'taking dredging as the main and regulation structures as the supplements' is put forward. Based on the rigid bed test and rigid-bed with sand test, and with consideration of the characteristics of the backwater river reach, the feasible regulation scheme is set forth, the effect of which has been proved fairly good.
