【摘要】：渤海灣曹妃甸近岸海區(qū)多個潮汐深槽與沙島相伴而生并構(gòu)成極為復(fù)雜的海岸動力地貌體系,而維護(hù)既有的灘槽宏觀格局是保持灘槽穩(wěn)定與合理開發(fā)布局的重要基礎(chǔ)。曹妃甸開發(fā)遵循因勢利導(dǎo)的原則,對淺灘與深槽進(jìn)行了科學(xué)保護(hù)和合理利用,通過尋找深水岸線開發(fā)、灘涂匡圍與環(huán)境影響之間的平衡點(diǎn),在開發(fā)合理規(guī)劃布局與維護(hù)灘槽動力地貌格局現(xiàn)狀之間實(shí)現(xiàn)了很好的協(xié)調(diào)性。工程實(shí)踐效果表明,由于曹妃甸開發(fā)布局規(guī)劃科學(xué)合理,沒有改變整個海區(qū)的灘槽動力地貌格局和潮汐深槽形成的動力機(jī)制,因而深槽及周邊海區(qū)在開發(fā)工程實(shí)施后穩(wěn)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.
