张家界市子午西路路基设计要点分析

Analysis of the Main Points of Subgrade Design of Ziwu West Road in Zhangjiajie City

由于张家界市地处山区地形地貌的特殊环境,道路路基常见填挖交界、陡坡、浸水等典型路基形式,在气候环境与车辆荷载的作用下,易发严重影响交通安全的系列结构性病害。结合山区道路的实践经验,论文简单分析了山区道路的主要病害形式及机理,重点针对上述3种典型路基,对张家界市子午西路进行以防控病害为目标的路基设计要点分析,提出需要注意的设计原则和工程措施,期望为相关技术人员提供参考。

Because Zhangjiajie City is located in the special environment of mountainous terrain and landform,the typical subgrade forms such as filling and digging junction,steep slope and immersion are common in road subgrade.Under the influence of climate environment and vehicle load,a series of structural diseases that seriously affect traffic safety are prone to occur.Combined with the practical experience of mountain roads,the paper simply analyzes the main disease forms and mechanisms of mountain roads,focusing on the above three typical subgrades,analyzes the key points of subgrade design of Ziwu West Road in Zhangjiajie,aiming at disease prevention and control,and puts forward the design principles and engineering measures that need to be paid attention to,hoping to provide reference for relevant technical personnel.
