Abstract: This paper studies westergaard and finite-element method to calculate curling stress. Using finite-element program CTO5, curling stress on concrete pavement is calculated. The relationship between thecurl ing stress and subgrade parameters is obtained,and the effect of the slab length and width on thecurling stress is analyed,the results have practical value to the design and construction of concrete pave-ment.

Key words: concrete pavement, temperature curling stress, subgrade and pavement, finite-element

摘要： 本文首先对威斯特卡德计算温度翘曲应力方法与有限元方法进行了对比研究，其次运用温度翘曲应力有限元程序ＣＴＯ５计算了水泥砼路面的温度翘曲应力，得出了温度翘曲应力与水泥砼路面的基层材料参数间的相互关系。并在此研究的基础上，分析了水泥砼路面的分块对温度翘曲应力的影响，其结论可供设计、施工单位参考。
