摘　　要：纵向裂缝是市政道路施工中常见病害,具有规模大、分布广和危害严重等特点。研究市政道路施工中路基纵向裂缝的发生发展规律,揭示路基纵向裂缝的发生机理十分必要。通过对市政道路施工中路基纵向裂缝的发生原因和预防保养进行研究,建立相关模型对市政道路施工中路基纵向裂缝发生机理分析,为路基纵向裂缝病害的研究和整治提供参考。Longitudinal cracks are a common disease in the construction of municipal roads, which have the characteristics of large scale, wide distribution and serious damage. It is necessary to study the occurrence and development of longitudinal cracks in subgrade in municipal road construction and reveal the mechanism of longitudinal cracks in subgrade. This paper studies the causes and preventive maintenance of longitudinal cracks in subgrade in municipal road construction, establishes related models to analyze the mechanism of longitudinal cracks in subgrade in municipal road construction, and provides references for the research and treatment of longitudinal cracks in subgrade.
