东江(河源至石龙段)航道整治研究技术难点分析
|
摘要
东江河源至石龙航道扩能升级工程拟通过航道整治,将该段航道等级提高至Ⅲ级,实现东江干流千吨级航道至河源,大幅提升东江航道的通过能力。从技术层面分析了东江(河源至石龙段)通过航道整治提高至Ⅲ级航道研究可能存在的5个难点问题:长河段各特征水位的确定、滩险特性及成因分析、整治原则的确定、航槽稳定性研究、梯级建设对航道条件的影响,为类似整治工程的研究提供积极的参考价值。
Dongjiang River( from Heyuan to Shilong Reach) waterway expansion and upgrading project with waterway regulation to Ⅲlevel channel will realize the kiloton channel of the Dongjiang trunk stream to the Heyuan reach and greatly improve the passageway capacity of the Dongjiang River. Difficult issues exiting possibly in Dongjiang River( form Heyuan to Shilong reach) with waterway regulation to Ⅲ level channel are technically analyzed. There are five difficult issues such as the determination of the characteristic water level in long river reach, the analysis of shoals characteristics and causes, the determination of regulation principles, the research on the stability of navigation channel, and the influence of cascade construction on the channel conditions. The paper provides positive reference value for the research of similar regulating engineering.
