船闸引航道口门区防淤措施研究

The Sedimentation Analysis of Entrance Area with Shiplock Approach Channel

船闸引航道口门区由于特殊的水力条件,其淤积是一个普遍存在的问题.重视泥沙淤积问题的严重性,认真做好前期的分析和研究,积极采取有效的工程措施和运行调度方案,对防止或减缓泥沙淤积,保证通航建筑物的正常使用是非常重要和有效的.借鉴几个已建船闸的经验教训,采用物理模型与数学模型相结合的方法,对一拟建航电枢纽船闸引航道口门区的泥沙淤积问题进行了分析和研究,并提出了以疏浚为主的防治工程措施和合理的运行调度方案.

Because of the particular hydraulic power condition of shiplock approach channel,its sedimentation is a common problem.Taking the sedimentation of bedload seriously,doing a good analysis and research in early stage and adopting effective engineering methods and dispatching scheme are very important for avoiding or reducing sedimentation and regular usage of navigation-traffic structure.Based on lessons from several built shiplocks,the paper adopts the method of mathematic model combining physical model,and ...
