津汉联络线高速互通立交设计安全评价

Safety Evaluation on Expressway Interchange Design of Tianjin-Wuhan Connecting Line

以津汉联络线高速互通立交项目为例,从匝道平纵线形、变速车道长度、分合流点视距、主线运行速度协调性等方面进行技术安全分析,从而检验互通立交方案的各项指标和运行安全水平。

Taking Tianjin-Wuhan Connecting Line Expressway Interchange Project as an example,this paper analyzes the technical safety from the horizontal and vertical alignment of ramp,the length of speed-change lane,the sight distance of separation and confluence points,and the coordination of main line operation speed so as to check out various indexes and operation safety level of interchange schemes.
