敞开式下沉道路立交设计实际案例分析

Analysis on Interchange Design of Open Sinking Road

摘要:

随着经济的发展，我国汽车保有量逐年增多，城市道路交通日显拥挤，道路网络建设日益错综复杂。为了缓解城市的交通压力，各地增加了各种各样设计的立体交叉桥、隧的建设，而立交桥对城市景观有较大的影响，特别是位于城市环境较为敏感的地区，由此会采用主要道路下沉实现立体交叉。目前来看，道路下沉主要分为两种，一种为被交路采用桥梁方式跨越地下道路；另一种为在下沉道路设置框架结构，而被交路位于框架结构的上方通行。通过实际案例分析采用放坡式边坡的下沉式道路的适用情况、对相关问题采取的措施及需要注意的事项等。

Abstract:

With the development of economy, the car ownership has increased year by year in China. The traffic of urban road is getting heavier, and the road network construction is becoming complex. In order to ease the traffic pressure of cities, various designed interchanges and tunnels are constructed in various places. But the interchanges have a greater impact on the urban landscape, especially in areas where the urban environment is more sensitive. Therefore, the main road subsidence will be used to achieve a three-dimensional intersection. At present, there are two types of road subsidence. One is that the crossed road crosses the underground road by bridge. The other is to set up a frame structure on the sinking road. And the road to be crossed is located above the frame structure. The application of the sinking road with sloping slope, the measures to be taken for related problems and the matters needing attention are analyzed through the actual cases.
