摘要
高速公路与地方道路交叉必须设置通道或天桥。根据规范要求,通道与天桥都有一定的净空要求,因此交叉方式的选择势必影响整条高速公路的平均填土量、占地等。在分析平原地区高速公路2种交叉方式利弊的基础上,计算比较了2种方式的经济性,提出了平原地区高速公路通道与天桥的选取原则,以保证高速公路经济合理性的同时能满足两侧居民的生产生活需求。
An underpass or overpass must be set when expressway crosses local roads.According to the specification requirements,underpass and overpass both have a certain clearance requirement.Hence,The choice of the ways is sure to influence the average filling height and land occupation of expressway.This paper analyzes the pros and cons of the two ways,and calculated the economy of the two ways of expressway in plain area.Thereby the selecting principle is proposed,to ensure the expressway economic and rationality and meet the daily needs of the residents.
