摘要
现以赵庄南沟串流区为例,分析了由于在初步设计修改阶段流域内修建了高速公路,改变了南水北调总干渠以上的水文情势,对串流片内的穿河建筑物规模和安全产生的影响。在初步设计修改阶段,根据最新的情况和研究结果,修改了交叉建筑物的规模和防洪水位等,保证了建筑物本身和总干渠的安全。
In this study, the over-flow area of Zhaozhuang Nan River is selected as an example. In the preliminary design phase, it has changed the hydrological regime above the main channel due to construction of the highway in the basin. Besides that, it also affects the scale and security of crossing-river buildings. In the preliminary design modification stage, it re-modifies the size and flood control water level of the building based on the latest situation in order to ensure the safety of the buildings and the main channel.
