摘要： 横向设施尤其是下穿通道的数量会影响到整条高速公路平均填土量，因此合理的横向通道设施设置须即能保证高速公路路基高度的降低，又能满足两侧居民的生产生活需求．本文对横向通道设施设置的影响因素进行了分析，确定了横向设施的最大间距应不大于居民可忍受的最大绕行距离;建立了针对人行天桥或人行通道、汽耕通道或跨线桥密度等不同使用功能的设施类型的密度函数;结合居民可忍受的最大绕行距离推算出通道的合理间距并拟定横向设施设置的备选方案；进一步基于综合绕行系数最小原则，建立横向设施选址优化模型，确定拟建高速公路横向设施的具体位置．最后以大广高速衡大段为例，应用该方法取得了良好的效果．

Abstract: Transverse passage facilities, especially the amount of the underpasses, always influences the average filling height of the whole expressway.Therefore, reasonable location of transverse passage facilities should not only ensure the reduction of the expressway embankment height but also meet the daily needs of the residents at both sides.Through analyzing the factors influencing the installation of transverse passage facilities, the paper develops the density models of transverse passage facilities respectively in view of the major functions of pedestrian overpass or underpass and traffic underpass or flyover.It further presents reasonable spacing and location alternatives in consideration of the longest tolerable detouring distance for residents.And then, it establishes the optimization model ro select the site of transverse passage facilities based on the principle of minimum synthetic detouring coefficient, and eventually determines the final location.In the end, the method is applied to the case of Hengshui-Daming Section on Daqing-Guangzhou Expressway, which is proved effective.

Key words: highway transportation, location optimization model, density model, transverse passage facilities, detouring coefficient
