摘　　要：以某平原区高速公路为研究对象,利用有限元软件建立计算模型,分析了半刚性基层裂缝扩展规律。同时,阐述了预切缝技术(预切缝间距、时间、深度等)和应力吸收层技术(材料组成、设计参数等)在控制半刚性基层反射裂缝中的应用。Taking a highway in a plain area as the research object,a calculation model was established by using finite element software to analyze the expansion law of cracks on the semi-rigid base.At the same time,the application of pre-cutting seam technology(pre-cutting seam spacing,time,depth,etc.)and stress absorption layer technology(material composition,design parameters,etc.)in the control of reflection cracks in semi-rigid base layers was elaborated.
