Study on the impact of cross-river engineering on sedimentary dynamic environment in Yulong Island, Shandong
-
摘要:
根据裕龙岛附近海域水文和地形等实测资料，采用数值模拟的方法，模拟了研究区跨河道工程建设前后的水动力、冲淤和水交换等沉积动力特征，探讨了跨河道工程建设对裕龙岛内部沉积动力环境的影响。结果表明，跨河道工程建设使裕龙岛内部水道潮流流速整体减小，最大减小量超过20 cm/s，减弱了水道内水动力环境；工程建设对水道内冲淤环境产生一定影响，改变了水道的微侵蚀环境，部分地区发生淤积，最大年淤积量超过2 cm；工程建设明显影响水道内水交换，造成水交换率下降，部分区域水交换率低于60%。整体而言，经一河、经二河建设桥梁，纬一河建设管涵对水道内沉积动力环境影响相对较小，符合工程建设的实际要求。海岸工程建设应优先考虑海洋环境保护，实现工程和环境的协调发展。
Abstract:With the hydrological and topographic data from sea area near Yulong Island, Shandong, the sedimentary dynamic patterns of current, erosion and deposition, water exchange rate before and after the cross-river engineering (bridges or tunnels) were simulated numerically, and the impact of the engineering on the internal sedimentary dynamic environment of the Yulong Island was discussed. Results show that the engineering would decrease the tidal current velocity in overall, and the maximum reduction is over 20 cm/s. This situation would weaken the hydrodynamic environment such as the erosion and deposition in waterways, and change the micro erosion environment. In some regions, siltation would occur and the maximum annual siltation is over 2cm. In addition, the project will influence the water exchange within waterway. The rate of water exchange would be reduced by less than 60% locally. As a whole, it is suggested to build bridges across Jingyi River and Jinger River, while to use pipe and culvert in Weiyi River would be the best option with a minimal impact, which accords with the actual requirements of engineering construction. Coastal engineering construction should prioritize marine environmental protection and achieve coordinated development between engineering and the environment.
