本文以横沙东滩促淤圈围(四期)工程为例,采用平面二维水流数学模型,根据工程的总平面布置,结合工程的特点和难点,分析不同施工顺序下各堤段水动力条件的变化情况,从而制定出对各堤段及周边水域影响最小的工程施工顺序,为工程的顺利实施提供技术支撑,同时也为类似中低滩促淤工程提供参考。
Taking the project of promoting sedimentation and silting (Phase IV) in Hengsha East Beach as an example, this paper uses plane two-dimensional flow mathematical model to analyze the hydrodynamics of each embankment under different construction sequences according to the general layout of the project and the characteristics and difficulties of the project Conditions of the changes in order to work out the embankment and the surrounding waters of the least impact on the construction sequence, to provide technical support for the smooth implementation of the project, but also for similar low-lying flood control projects to provide a reference.
