【摘要】：渤海湾曹妃甸近岸海区多个潮汐深槽与沙岛相伴而生并构成极为复杂的海岸动力地貌体系,而维护既有的滩槽宏观格局是保持滩槽稳定与合理开发布局的重要基础。曹妃甸开发遵循因势利导的原则,对浅滩与深槽进行了科学保护和合理利用,通过寻找深水岸线开发、滩涂匡围与环境影响之间的平衡点,在开发合理规划布局与维护滩槽动力地貌格局现状之间实现了很好的协调性。工程实践效果表明,由于曹妃甸开发布局规划科学合理,没有改变整个海区的滩槽动力地貌格局和潮汐深槽形成的动力机制,因而深槽及周边海区在开发工程实施后稳定性良好。
[Abstract]:Many tidal deep troughs in the Caofeidian coastal area of Bohai Bay are concomitant with the sandy islands and form a very complex coastal dynamic geomorphological system. The maintenance of the existing macro-pattern of beach and trough is an important basis to maintain the stability and rational development layout of the shoal channel. The development of Caofeidian follows the principle of favorable guidance in accordance with the situation and scientific protection and rational utilization of the shoal and deep trough. By looking for the balance point between the development of deep water shoreline and the environmental impact, a good coordination is achieved between the rational layout of the development and the maintenance of the present situation of the dynamic geomorphological pattern of the beach and trough. The engineering practice results show that. Because the development layout planning of Caofeidian is scientific and reasonable, it has not changed the dynamic geomorphological pattern of beach and trough and the dynamic mechanism of tidal deep trough in the whole sea area, so the stability of deep trough and surrounding sea area is good after the implementation of development project.
