摘要:
天然游泳场的冲淤变化是影响边滩游泳场正常稳定运营的关键。首先分析闽江西河流态和输沙特征,表明闽江西河边滩及附近河段的输沙不平衡将很大程度上危及该天然游泳场的边滩稳定性。在此分析结论的基础上,结合数值模拟技术,计算出工程整治措施对边滩游泳场及其附近河段冲淤变化的影响。研究结果表明:对旧洪山大桥桥下深槽进行抛石填充以及对游泳场边滩进行平整能够有效的抑制游泳场的弯道环流,改善本河段的流速分布,从而改善边滩河段纵向及横向的输沙不平衡的现象。因此,工程措施能够减弱游泳场上游淤积下游冲刷的现状,对促进边滩的稳定起到积极的作用。
Abstract:
The change of the erosion and siltation of the beach was the key factor in the safety of the beach swimming pool.Based on the full analysis of Minjiang West river flow pattern and sediment characteristics, it was found that the sediment transportation imbalance would endanger the stability of the beach of the natural swimming pool.On the basis of the analysis conclusion and the technology of numerical simulation, the influence of engineering control measures on the change of the erosion and silting of the beach swimming pool and the nearby river was calculated.The research results showed that the filling deep groove by stone under the old Hongshan bridge and the leveling of the beach could effectively restrain the loop flow of the swimming pool and smooth the flow of the pool at the edge beach so as to reduce silting strength of edge beach and optimize the velocity distribution, restrain the river beach sediment of longitudinal and transverse uneven phenomenon.Therefore, engineering measures could reduce the current situation of the upstream siltation and downstream erosion of the swimming pool and play a positive role in promoting the stability of the beach.
