摘要
武汉河段为长江中下游16个第一类重点整治河段之一,水力冲刷条件复杂.通过实测资料分析三峡建库前后的来水来沙变化,并进行河道与航道演变分析,再依据已有航道整治工程实践经验,系统总结出提升航道等级必须要因势利导、相机实施整治工程,复杂水力冲刷下河槽与航道等级提升后的航槽衔接方法分为防护型衔接和建设型衔接2类.防护型衔接主要分为守护现有底坡边滩和稳定改善汊道航槽状态2种衔接措施,建设型衔接主要分为塞支强干、维持一汊通航和控导汊道分流、选择2汊通航2种衔接措施.
Wuhan reach is one of the 16 first grade reaches that need reinforcement in the middle and lower of the Yangtze River; and its hydraulic scour condition is complicated. Using the measured data, the author analyzes the changes of coming water and sand before and after the construction of the Three Gorges Reservoir, and analyzes the evolution of river and channel. On the basis of existing waterway regulation engineering construction experience, the author summarizes systematically that improving the channel grade must make the best use of the circumstances and implement regulation poject in response to the situation. The connecting method of river in the condition of complicated hydraulic scour to navigation channel with elevated channel grade can be mainly divided into two categories, i.e. protective type and constructive type. The protective type mainly include protecting existing base slopes and marginal banks and optimizing branching channels. The constructive type mainly include jamming tributaries to strengthen main stream and replanning new channels.
