摘　　要：常泰过江通道直接联系江苏常州新北区与泰兴市,是《江苏省高速公路网规划(2017-2035)》中15座高速公路过江通道之一,也是《长江经济带立体综合交通走廊规划(2014-2020)》中江苏省14条过江通道之一。项目从国家规划、公路及铁路过江需求、节约过江通道资源等因素出发推荐采用公铁合建形式过江;在跨越长江的位置选择中,推荐从宏锦物流码头上游、录安洲边防站与魏村水厂之间穿过的D过江线位。文章以此为基础,对推荐的D过江线位桥梁方案和隧道方案进行深入研究。经过论证比较,隧道方案在通航、防洪、环保、特殊天气应对方面略有优势;但桥梁方案在功能、运营安全、防灾救援、管养与成本方面桥梁方案优于隧道方案。且由于合建的多功能桥梁方案在过江资源占用上实现了1+1+1<3的集约、节约目标,因此最终推荐多功能合一的桥梁过江方案。Changtai River Crossing channel is directly connected with Changzhou New North District and Taixing City. It is one of the 15 highway crossing channels in Jiangsu Province Expressway Network Planning(2017-2035) and one of the 14river crossing channels in Yangtze Economic Belt Three-dimensional Comprehensive Transportation Corridor Planning(2014-2020).Based on national planning, demand of road and railway, saving river crossing channel resources and other factors,the project is recommended to adopt the form of highway and railway crossing the river. In the selection of the location across the Yangtze River, it is recommended to cross the D river crossing line from the upstream of Hongjin Logistics terminal and between Lu ’anzhou Border Defense station and Weicun Water Works.Based on this, the paper conducts in-depth research on the bridge scheme and tunnel scheme recommended for D river crossing line. Through comparison and demonstration,the tunnel scheme has slight advantages in navigation, flood control, environmental protection and special weather response.However, the bridge scheme is superior to the tunnel scheme in functions, operation safety, disaster prevention and rescue,management and maintenance and cost.In addition, as the multi-functional bridge scheme has realized the intensive and economical goals of 1+1+1<3 in the river crossing resource occupation, the bridge crossing scheme with integrated multifunctions is finally recommended.
