西攀高速公路蒲坝大桥路段交通安全因素分析

Analysis of Traffic Safety Factors in Puba Bridge Section of Xichang—Panzhihua Expressway

以西昌—攀枝花高速公路蒲坝大桥段为研究对象,从设计资料入手,应用道路安全工程原理,从线形安全性、路面排水性能、护栏衔接等方面对该桥段的潜在危险因素进行分析和鉴别,提出相应的整改措施,期望能为其他高速公路类似安全问题的处理提供借鉴。

By taking the Puba Bridge section of Xichang---Panzhihua Expressway as the object of study and starting from the design data, this paper analyzes and identifies the potential risk factors of this section from the aspects such as linear safety, pavement drainage performance and guardrail connecting segnents, etc. by means of principle of road safety engineering, puts forward corresponding corrective measures with expectation for providing references for treatment of similar safety problems in other expressways.
