摘　　要：在互通式立交设计中,首先需要考虑适配当地城镇的发展以及路网规划,从而确定出互通立交布设的位置以及数量。因此互通立交的设计既要有利于促进沿线区域的经济发展,吸引以及缓解交通量,提高公路投资效益,同时也需要考虑控制投资规模,以及降低后续运营成本等因素进行方案研究比选。本研究主要介绍湖南省某高速公路与江衫高速交叉节点金州枢纽互通立交的设计方案比选研究,针对该互通立交项目的建设必要性以及周边客观条件,从平纵面指标设计、方案设计比选等多个方面着重分析了该枢纽互通总体设计方案,方便后续为同类型互通设计提供参考。The design of interchanges needs to adapt to the development of local towns and road network planning,and determine the location and quantity of interchanges.Therefore,it is necessary to not only promote the economic development along the expressway,attract and alleviate traffic volume,improve the investment efficiency of the highway,but also consider factors such as controlling investment scale and reducing subsequent operating costs for scheme research and comparison.This study introduces the research on the design scheme of the Jinzhou Interchange at the intersection of the G4 Beijing Hong Kong Macao Expressway and Jiangshan Expressway in Hunan Province.In response to the functional positioning and construction necessity of the interchange project,the overall design scheme of the interchange is analyzed from multiple aspects such as interchange site selection,scheme design comparison,and horizontal and vertical index design,which is convenient for providing reference for similar interchange designs in the future.
