摘　　要：文章以某高速公路互通立交为工程实例,考虑项目地形、地物和用地条件等因素,提出并对比了两种不同的互通立交设计方案,解决了高速主线与被交叉道路高差较大造成匝道展线较长从而导致用地面积较大及用地切割等问题。在满足功能性需求的同时,喇叭形互通立交方案在视觉上更紧凑美观,降低了对周边环境的影响,体现了环境保护和可持续发展的设计理念。Taking an expressway interchange as the engineering example,considering the factors such as terrain,ground object and land conditions of the project,this paper puts forward and compares two different interchange design schemes,which solves the problems such as large land area and land cutting caused by the long ramp line due to the large height difference between the expressway main line and the crossed roads.While meeting the functional requirements,the trumpet-shaped interchange scheme is more compact and beautiful in vision,reduces the influence on the surrounding environment,and reflects the design concept of environmental protection and sustainable development.
