摘要
随着长江口北港河道主泓不断呈反"S"形发展,堡镇岸段原丁坝群坝头附近冲刷深度加大、坝间滩地冲刷后退,对大堤安全构成一定威胁;需采取工程措施补救,保护坝头和坝间滩地稳定。本文采用MIKE 21数学模型,模拟了北港堡镇岸段的水动力场,并比较两种坝头保护方案对水动力场的干预作用,推荐了合理的工程方案。
As the main North Channel of the Yangtze Estuary has been reversed to＇S-shape＇,the bottomland around head of groynes at Baozhen Coast has been scoured deeper and the bottomland between groynes has been scoured back, which threats the sea dike. So it has to take remedial measures to protect the head and bottomland between groynes.In this paper, MIKE 21 is used to simulate hydrodynamic model, which simulates the hydrodynamic field at the Baozhen Coast.The paper compares the intervention effect by two kinds of remedial measures in protection of the head of groyne, and recommends, engineering solutions .
