摘要:
为了研究热膨胀系数对水泥混凝土路面结构设计的影响,根据我国规范分析了热膨胀系数对面层板温度应力的影响,同时采用美国力学经验设计法分析了热膨胀系数对水泥混凝土路面横缝错台量的影响.结果表明:热膨胀系数对接缝传荷能力以及板角翘曲变形的影响会直接改变水泥混凝土路面设计厚度.因此,在水泥混凝土路面设计中引入热膨胀系数参数意义重大.
Abstract:
In order to research the effects of coefficient of thermal expansion ( CTE) on the PCC pavement de-sign，some efforts have been done. According to the PCC pavement design standard in our country ，the influ-ence of CTE on the temperature stress is analyzed , and the M-E design method is used to analyses the influ-ence of CTE on transverse joint faulting. The conclusion is drawn that CTE has a great impact on the designingof pavement thickness especially on the joint load transfer and the warping of slab corner. So introducing theparameter of CTE to the PCC pavement design is of great significance.
