| 摘 要： | 研究了茅家港环抱式突堤航道防护工程对茅家港犀段的海犀水动力和海犀地貌的影响，分析了该岸段海犀水动力变化和海岸地貌演变的原因，结果表明，堤内和东堤外侧的水动力变弱，滩面淤积；西堤外侧的水动力变强，滩面冲蚀；口门处的水动力增强，航道位置稳定且冲蚀加深；口门以外的水动力未变化，航道不稳定．

| Abstract: | In this paper, the effect of Maojiagang combined jetty waterway protection works on hydrodynamic force and geomorphology in the Maojiagang coastal area is studied, and the causes for the hydrodynamic changes and geomorphological evolutions in the coastal area are analyzed. It is shown from the study results that the hydrodynamic force inside the jetties and outside the east jetty is weakened to result in the beach face aggradation, the hydrodynamic force outside the west jetty is strengthened to result in the beach face erosion, the hydrodynamic force at the basin entrance is strengthened to make the waterway stable and deeper by erosion, and the hydrodynamic force off the basin entrance is unchanged to make the waterway unstable. |
