结合国内外已有的研究成果及厦门八一大道连接沈海高速公路的互通立交方案设计,对互通式立交的建设方案的安全性影响因素进行分析。研究过程中一方面在设计方案提出前,分析互通式立交位置确定时考虑平面线形、竖曲线、纵坡和主线纵坡等因素对行车安全的影响,另一方面在设计方案提出后,分析立交方案提出安全性核查具体方法。其研究结论与成果可供工程技术人员在进行类似互通式立交工程方案设计时参考。
Based on the existing research results both at home and abroad and the design of the interchange scheme of Xiamen Bayi Avenue connecting Shen-Hai Expressway, the influencing factors of the safety of the construction scheme of the interchange are analyzed. In the process of research, on the one hand, before the design proposal was put forward, the influence of traffic safety on the traffic safety should be considered in determining the position of interchange, such as flat line, vertical curve, longitudinal slope and main longitudinal slope; on the other hand, after the design plan was proposed, Program put forward safety verification specific methods. The conclusions and achievements of the study are available to engineers and technicians for reference when designing similar interchange project.
