摘要
本文用实验方法研究了刚性路面热胀屈曲的力学机制与临界铺设温差。针对有机玻璃和水泥混凝土两种路面模型,本文分别采用两种方法测量临界压力。作者提出了一种新的测量物体离面转角的方法——载波干涉法,这为拓广图象光载波工作作了有益的尝试。
In this paper, the thermal buckling of concrete pavements as well as the critical temperature difference are investigated by using experimental methods. Two experimental methods, namely, the photocarrier interference methoda new method and the mechanical test are used for the thermal buckling tests of two kinds of models the model made of plexiglass and the model made of concrete. It is believed that it is the pioneering work for the photocarrier interference method in the present research.
