摘要
水泥混凝土路面直接暴露在大气之中,一年四季大气温度周期性的变化以及每一天白昼黑夜气温的变化,使得混凝土路面的温度也随之产生周期性的变化。本文论述了水泥混凝土路面温度应力诞生与发展的必然性,全面系统介绍了国内外温度应力计算公式的发展历程,提出了应进一步开展的研究工作。
Cement concrete pavements are normally directly exposed to the atmophere. The periodic changes of air temperature over years cause the periodic temperature changes of concrete pavements. The article introduces the ne- cessity of the creation and development of the temperature stress of cement concrete pavement ,and introduces the de- velopment process of the calculating formula for temperature stress at home and abroad comprehensively and systemat- ically.At last,we have an outlook for the further reseach.
