| 摘 要： | 以线粘弹性模型理论和有限元初应变增量法为基础，提出了考虑材料粘弹性性质的水泥混凝土路面温度翘曲应力的数值计算方法，并编制了相应的计算机程序ＶＴ０．５运用该程序分析了两种地基上的混凝土路面板在温度翘曲变形受到地基反力约束时产生的翘曲应力，得到了较仅考虑材料弹性特征时更为合理的结果，为完善水泥混凝土路面温度翘曲应力的计算提供了科学的方法。

| Abstract: | According to visco elastic model and initial strain incremental finite element method, the numerical temperature curling stresses approach taken into material of viscoelastic character accunt is presented, and computer program VT05 is drawn up. Using the program, curling stresses on two foundations are calculated. It is more reasonable results in comparion with which is taken into material of elastic character. This approach is supplied to perfect curling stresses calculation. |
