枢纽互通式立交是高速公路建设中的一个重要组成，其中，互通式立交方案的选择是其关键环节。以实际工程为例，介绍了某高速枢纽互通式立交初步设计选型过程，并尝试用综合量化的评价方法进行方案选择，供工程师在设计中参考。%Hub interchange is an important part in highway construction,in which the selection of interchange programs is the key link. This paper takes an practical engineering as an example,introduces the alternative options process of a highway terminal interchange in the preliminary design stage,and tries to select scheme with the comprehensive quantitative evaluation method. The study would provide certain reference for the freeway designer.
