为研究厦门招银开发区围垦方案实施前后,对联合循环电厂塔角及岛美取排水口海区水深稳定性的影响.本研究在前人大量现场勘测及研究的基础上,通过对大磐浅滩进行现场调查、取样和样品粒度分析,重点对浅滩、沙嘴与深槽不同级配泥沙进行了水力特性试验分析。并结合调查和实验数据资料,从地貌学角度对电厂排水影响进行了分析。 研究证明岛美和塔角厂址在大磐湾不围垦的情况下,滩槽的演变对电厂取排水口无影响。但围垦后,将导致深槽水流的减少,流速减弱,塔角处水深将略为变浅。岛美方案优于塔角方案。厂址应综合比选,加以确定。
In order to study the influence of the tower angle of the combined cycle power plant and the water depth stability of the drainage area of the island of the United States before and after the implementation of the reclamation project in Xiamen CMB Development Zone.Based on a large number of previous site surveys and studies, Field investigation, sampling and grain size analysis were carried out. The hydraulic characteristics of different levels of silt in shoal, sand spout and deep trough were analyzed emphatically. Combined with the survey and experimental data, the influence of power plant drainage on geomorphology was analyzed. Studies have proved that the island beach and tower angle site in Dabei Bay without reclamation, the evolution of the trough on the power plant outlet has no effect. However, after reclamation, it will result in a decrease of water flow in deep troughs and a decrease of flow velocity, and the water depth at tower angles will be slightly shallower. Island program is better than tower angle program. The site should be comprehensive comparison and selection, to be identified.
