受沿岸流、潮流、径流等动力因素影响,河口水域水动力结构非常复杂。基于数值模拟方法,研究了台山海域腰鼓岬角动力结构并优化了某核电厂取排水口布置方案。结果表明,工程布置方案受粤西沿岸流、珠江下泄径流、腰鼓岬角非稳定的辐散与辐合流、珠江河口高盐陆架水过程等复杂动力过程影响;粤西沿岸流、珠江洪季下泄径流及落潮期间的辐散与辐合流结构,均存在明显的西向输运现象,因此新建核电站排水口不宜与西侧台山火电厂排水口过近,而宜向北布置,以避免影响现有电厂取水温升;方案1排水口布置在腰鼓岬角以北,取水口布置在河口高盐低温陆架水区域,是较优方案。其他方案则需加大取、排水口距离或开辟新的热水通道,降低自身排水对取水口的影响,才能使方案成立。 Affected by the dynamic factors such as coastal flow, tidal current and runoff, the hydrodynamic structure in the estuary waters is very complicated. Based on the numerical simulation method, the dynamic structure of the waist drumhead in Taishan sea area is studied and the layout of the outlet of a certain nuclear power plant is optimized. The results show that the layout of the project is affected by the complicated dynamic processes such as the flow of the coast of Guangdong, the discharge of the Pearl River, the unsteady divergence and convergence of the rock drum headland and the high salt shelf water of the Pearl River Estuary. And the ebb and flow of convergent flow during ebb tide, there are obvious westward transport phenomena. Therefore, it is not appropriate for the newly built outlet of a nuclear power station to be too close to the outlet of the Taishan Thermal Power Plant on the west side and should be arranged to the north in order to avoid affecting the water intake of the existing power plant Temperature rise; Scenario 1 Arranged in the headwaters of the headwaters North promontory, intake located in estuarine high salt water shelf area, is the better solution. Other programs need to increase take, the distance between drainage outlets or open up new channels for hot water to reduce the impact of drainage on the water intake in order to make the project set up.
