| 摘 要： | 建立了湛江湾泥沙数学模型,模拟了湛江湾海床冲淤演变,模拟结果表明,湛江湾海床较为稳定,年冲淤强度小,模拟冲淤分布与历史海图资料得出的长期演变趋势符合。模型用于湛江湾围填工程对海床冲淤变化的影响预测,结果表明工程后海床冲淤强度没有明显的改变。另外,优选了围填方案,估计了港池的淤积强度。

| Abstract: | This paper established a sediment transport model in the Zhanjiang Bay, and simulated the seabed evolutions of erosion and accretion in the Janjang Bay. The results show that, before the reclamation engineering, the seabed in the Bay is relatively stable, annual erosion and accretion rates being low there. The distribution of the simulated erosion and accretion rate also agrees with the long-term evolution tendency derived from the Zhanjiang Bay charts of various historic times. The model is used to predict the effects of tideland reclamation coastline on the seabed erosion and accretion. The predicting simulations show that there are no significant changes in seabed erosion and accretion rates after the reclamation engineering. Besides, this model is used to optimize reclamation projects and estimate the annual accretion rate at the harbor basin. |
