高速公路交通安全设施养护设计研究

Design research on highway traffic safety facilities maintenance

高速公路安全设施设计大部分是依据JTJ 074-1994进行设计和施工的,不符合当前规范和政策,需要更换和更名;增加的高速公路使城市周边互通增多了,出口标志信息需规范命名,对损坏、刮蹭、遮挡标志的更换或移位;优化标线渠化,引导车辆安全顺利行驶;对护栏提出了四种养护方案,供同类工程参考。

The highway safety facilities design is mostly based on JTJ 074 - 1994 to carry on the design and construction, is not in conformity with the current standard and policy, need to be replaced and changed its name; Each increase of highway make interfiow around cities increased, exit sign information should be standard named, the sign be damaged, scratched or shaded should be changed or shifted; Optimized marking canalization, guided vehicles running smoothly; For barrier put forward four kinds of maintenance projects, provide the reference for the similar projects.
