一种跨江桥梁与滨江道路相交叉的新型互通式立交形态研究

Study on a New Interchange Form of Intersecting River-crossing Bridge and Riverside Road

一般河流穿越城市,在河流两侧基本都敷设有滨江道路。随着城市的扩张,为支撑城市空间拓展和经济发展,必须首先发展交通。为沟通江河两侧城区,需建设跨江桥梁或越江隧道。滨江道路一般距离防洪堤较近,现提出一种在诸多限制条件下的新型跨江桥梁与滨江道路相交叉的互通式立交形态。对此,着重阐述其背景技术、滨江立交所需解决问题、适用条件、功能定位、技术标准和详细方案。

Generally, when rivers pass through cities, the riverside roads are basically laid on both sides of the rivers. With the expansion of cities, in order to support the expansion of urban space and the development of economy, the corresponding traffic goes first. In order to link the urban areas on both sides of the river, it is necessary to build bridges or tunnels across the river. The riverside road is usually close to the flood control wall. A new interchange form of intersecting the river-crossing bridge and riverside road under many restricted conditions is put forward. Therefore, the background technology, problems to be solved for riverside interchange, application conditions, functional orientation, technical standards and detailed scheme of the project are specially expounded.
