川西山区等级公路安全设施特色设计

Characteristics Design of Safety Facilities of Grade Highway in Mountainous Areas of Western Sichuan

我国川西高原地区,其特殊的地理条件和极端恶劣的自然环境条件,严重影响高原公路的行车安全。同时高原地区特有的自然景观和人文风俗,又吸引大批游客前往。山区等级公路的安全设施依靠现有的国标、规范等不能完全满足精细化的设计要求。针对川西山区公路的道路特征和文化特征,对山区安全设施从标志、护栏、标线上均提出了与环境景观相互协调的特色设计,以为类似工程提供借鉴。

The special geographical conditions and extremely harsh natural environment conditions in the western Sichuan plateau area seriously affect the traffic safety of highway on the plateau.At the same time,the unique natural landscape and human customs in the plateau area attract a large number of tourists.The safety facilities of grade roads in mountainous areas depend on the existing national standards and specifications,which can not fully meet the refined design requirements.In view of the road and cultural characteristics of mountain highway in Western Sichuan,this paper puts forward the characteristic design of coordination with environmental landscape for the safety facilities in mountain areas from signs,guardrails and marking lines,to provide a reference for similar projects.
