| 摘 要： | 接缝是水泥混凝土路面的重要结构,同时也是水泥混凝土路面的薄弱环节。在调查分析水泥混凝土路面接缝类病害的基础上,指出接缝张开量大小与填缝料变形相匹配是保证接缝具有良好使用性能的重要因素之一,进而系统分析温度状况、湿度状况、基层类型、接缝间距、车辆荷载对接缝张开量的影响,为水泥混凝土路面接缝张开量数值分析敏感性因素提供参考。

| Abstract: | Joints are important structures of cement concrete pavement, but also are weak positions of ce- ment concrete pavement. After joint diseases of cement concrete pavement have been investigated and ana- lyzed, it has pointed out that one important reason ensures the good performance of joints, that is the size of JOD is to match with the deformation of joint filler. And then the influence factors of temperature, hu- midity, base type, slab size, traffic load are analyzed, and the results provide the potential for determining the sensitivity factors when the JOD for cement concrete pavement is numerically analyzed. |
