高速公路穿越蓄滞洪区路段的选线方法探讨——以邢衡高速公路邢台段为例

针对穿越蓄滞洪区的高速公路设计问题,根据二维不恒定流数学模型法等水利计算方法,对蓄滞洪区内高速公路工程修建前后的蓄滞洪过程进行了数值模拟.从蓄滞洪区防洪通道的安全畅通、高速公路自身的防洪安全、沿线村镇防洪安全等方面,提出对高速公路穿越蓄滞洪区路段的新设计思路和选线方法.

Line Selection Method of Expressway Passing Through Flood Storage and Detention Region -Taking Xingtai Section of Expressway from Xingtai to Hengshui as an Example

According to the design problems of expressway crossing storage and detention region, based on hydrology calculating method of two-dimensional non-constant current mathematical model, numerical simulation is carried out to the process of storage and detention before and after building the expressway. From the aspects of safety and smoothness of flood prevention channel, flood prevention safety of freeway itself and flood prevention safety of village along the expressway in flood storage and detention region, the paper puts forward a new design idea and line selection method of expressway crossing storage and detention region.
