Abstract: Aiming at the drawback that the existing analysis method for thermal stress of CRCP can't fully reflect its actual loading conditions, a calculation thought w ich can reflect the actual displacements of each slab section is proposed. A general analytic solution for thermal stress of CRCP is deduced under the effect of temperature reduction and temperature gradient. By means of the analytic solution, the stress and displacements of CRCP caused by temperature change at any point of the whole road can be calculated. Through the comparison of the finite element solution, the proposed solution is found to be more reasonable, feasible and accurate

摘要： 针对现行公路水泥混凝土路面设计规范推荐的连续配筋混凝土路面(CRCP)温度应力计算方法不能充分 反映CRCP实际受力条件的弊端,提出了考虑连续配筋混凝土路面(CRCP)板端部实际位移情况的计算思路。推 导了降温和温度梯度作用下,连续配筋混凝土路面(CRCP)温度应力的通用解析解。利用该解析解,可以计算连续 配筋混凝土路面(CRCP)任一点由温度变化引起的应力、位移值,通过与有限元解对比表明,提出的解析解准确、合 理,符合工程实际。
