以杭州湾北部奉贤海水运动中心工程为例,利用潮汐变化采用引排水建筑物实现引清调水,解决淤泥质海滩建设人工海滨浴场难题。根据工程规模和自然条件等确定引排水量,并利用MIKE21-FM软件模拟计算水库在不同工况下置换水体的流场变化,提出理论最优调水方案。研究结果显示,利用潮汐引排水可以较好维持人工海滨浴场水质,换水周期建议为1月为宜;引排水口门计算流速较大,建议采取保护一定的防冲保护措施。
Taking the project of Fengxian seawater sports center in the north of Hangzhou Bay as an example, the drainage and diversion structures are adopted to realize the diversion and diversion of water using the tidal changes to solve the artificial bathing beach problems of the muddy beaches. According to the project size and natural conditions to determine the amount of drainage, and the use of MIKE21-FM software to simulate the displacement of reservoirs in different conditions of the replacement of the flow field changes, the theory of optimal water transfer program. The results show that the use of tide drainage can be better to maintain artificial beach water quality, water cycle is recommended for the January is appropriate; drainage outlet gate flow rate is relatively large, it is recommended to take some protection against the impact of protection measures.
