摘要
以永靖至大河家高速公路项目中,莲花枢纽互通式立交为研究对象,根据地形、地质、工程规模、桥梁施工难易性、立交出入口与隧道洞口净距等制约因素,对该互通立交的形式、位置的选择及匝道的布设进行多方案比选研究,对于今后同类工程项目的实施具有重要意义。
In the Yongjing-Dahejia Expressway project,the Lotus Junction Interchange is used as the research object.Based on the constraints of topography,geology,project scale,bridge construction difficulty,and the clear distance between the entrance and exit of the interchange and the tunnel cavity,the selection of the form and location of the interchange and the layout of the ramp are studied in multiple options to for similar projects in the future.
