摘　　要：采用块体离散元方法,分析了一定厚度加铺层情况下,不同接缝宽度对加铺层的受力影响,确定了旧水泥路面改造处理的临界接缝宽度理论标准;并在确认该临界宽度后计算了最佳的加铺层厚度,为旧水泥路面改造处理设计提供相关理论指导。The block discrete element method was used to analyze the stress effects of different joint width on the asphalt overlay which under a certain thickness. And the critical of the old cement concrete pavement joint width standard theory was determined for renovating and treatment. The optimum overlay thickness was calculated after confirming the critical width. It provides theoretical guidance for the old cement concrete pavement about renovating and treatment design.

关 键 词：水泥路面加铺 临界接缝宽度 块体离散元 力学响应
