摘　　要：西部寒旱地区海拔较高、气候恶劣,在干湿冻融循环、冷热交替、水分和外部荷载等因素的影响下工程地质会发生变化,使得公路发生不同种类和程度的病害影响,路面开裂是公路病害最常见的类型。对于西部寒旱地区公路路面开裂病害的类型和成因进行分析,包括低温收缩开裂、变形开裂、剪切开裂、反射开裂、疲劳开裂等,对西部寒旱地区公路施工技术措施进行研究。The altitude is higher and the climate is awful in the western cold and dry regions. The engineering geology can change under the influence of dry-wet and freezing-thawing cycles, alternate cooling and heating, moisture and outer load, which will make the highways influenced by the different kinds and degrees of faults. The pavement cracking is the most common type of highway fault. The article analyzes the type and cause of highway pavement cracking fault in the western cold and dry regions including the low-temperature shrinkage cracking, deformation cracking, shear cracking, reflex cracking and fatigue cracking, and studies the construction technology measures of highways in the western cold and dry regions.
