刚性路面板热胀屈曲的理论分析

AN ANALYSIS OF THE THERMAL STABILITY OF CONCRET PAVEMENT SLABS

本文分析了水泥混凝土路面板在温度场作用下热胀屈曲的力学机制。采用摄动理论,本文导出了路面板临界铺设温差的渐近表达式并给出了误差分析。

In this paper, an analysis of the thermal buckling of concret pavement slabs is given. By the perturbation method, the formula of the critical temperature difference may be found and the error of which may also be estimated.
