摘要
根据有限元位移法、粘弹性模型和Goodman模型理论,研究了水泥混凝土机场双层道面(考虑三种结合方式:直接式、结合式以及分离式)的温度翘曲应力.运用有限元初应变增量法,编制了考虑材料粘弹性的水泥混凝土道面温度翘曲应力的计算机程序VT23.最后,运用该程序,计算了直接式双层道面的温度翘曲应力,并经某机场的现场实验证明其计算结果的正确性.为计算水泥混凝土道面温度翘曲应力提供了科学而有效的手段.
The formulas for calculating temperature curling stresses of double-layer (direct, bonded and separate) airport pavement were derived by using the finite elements method, vis-coelastic theory and Goodman model theory, from which the relevant computer program VT23 was developed by way of the initial strain incremental finite elements method. Finally, the temperature curling stresses of double-layer (direct) airport pavement were figured out by employing computer programs VT23, which were verified by in-situ measurements of an existing airport, with which the effective method on correct calculation of temperature curling stresses of airport pavement was provided.
