高速公路互通式立交安全性评价及设计研究

Safety Evaluation and Design Study of Expressway Interchange

互通式立交借助自身多层立体的结构形式疏导着路网内的交通运输,通过采用合理的设计方案,互通式立交有助于推进交通运输的安全性、功能性与经济性,并对路网建设的长期规划起到促进作用,带动建设沿线的经济、生态发展。在这样的背景下,对互通式立交的安全性进行评价并优化设计就成为了工作的关键。本文主要从高速公路互通式立交安全性的影响因素和评价要点出发,探讨了互通式立交设计的对策,以期能够为我国高速公路互通式立交建设提供参考和借鉴。

Interchange helps to promote the safety,functionality and economy of transportation by adopting a reasonable design scheme,and promotes the long-term planning of road network construction,driving the economic and ecological development along the construction line.In this context,evaluating the safety of interchange and optimizing the design becomes the key to the work.This paper mainly discusses the countermeasures of interchange design from the influencing factors and evaluation points of highway interchange safety,to provide reference for the construction of expressway interchange in China.
