湘江某河段航道整治的研究

Study on Channel Regulation of Some Sections of Xiangjiang River

本文通过对湘江某河段原型测量资料的整理和定、动床模型试验,对该河段河道基本特性、河床冲淤规律及沙质推移质运行特点进行了研究;提出了单一和分汉河段沙卵石浅滩的整治原则和工程措施,通过模型试验获得了最佳整治方案。

Based on the analysis of the field data and the tests of physical models with fixed and movable beds for some sections of Xiangjiang River, the river regime, the fluvial Processes and the charecteristics of bedload transport were studied in this paper. Principles and measures of the regulation for sand—graved shoals in single and branched reaches were also discribed. By the model tests, the best ragulation scheme was obtained.
