摘　　要：互通式立交的线形布设是一段或多段复合型曲线组合而成的平面结果,作为交通流转向枢纽,互通式立交平面线形的组合型式决定了与其线形匹配的运行速度。通过速度协调性分析计算来验证平面设计中采用的线形组合与其所匹配运行速度是否安全、连续,可判断互通平面的线形布设是否科学合理。The linearity layout of interchange is the result of a plane combining one or more composite curves.As a traffic flow turning hub,the combination type of interchange plane linearity determines the operation speed matching with its linearity.Through the speed coordination analysis and calculation,the safety and continuity of the linearity combination used in the plane design and its matching operation speed can be verified,so as to judge whether the linearity layout of interchange plane is scientific and reasonable or not.

关 键 词：协调性分析 立交平面 互通式立体交叉
