本文根据单层混凝土路面板温度状况测定结果,对双层混凝土路面的温度状况进行了分析,提出了双层混凝土路面板温度梯度计算公式,从而根据单层板温度梯度推荐值可以计算双层板的温度梯度。文章还按照分析双层混凝土路面荷载应力类似的方法。进行了一定温度梯度下温度沿板厚呈线性分布的双层混凝土路面翘曲应力分析。实际温度沿板厚呈曲线分布,对此按Timoshenko理论计算了附加内应力。最后得出温度沿板厚呈曲线分布时双层混凝土路面的温度翘曲应力。
According to the temperature measurement results of single-layer concrete pavement, the paper analyzes the temperature condition of double-layer concrete pavement and puts forward the formula of temperature gradient of double-layer concrete pavement. According to the recommended value of single-layer temperature gradient, The temperature gradient. The article also follows the method of analyzing the load stress of double-layer concrete pavement. The warping stress analysis of double concrete pavement with temperature distribution along the thickness of the slab at a certain temperature gradient was carried out. The actual temperature is curvilinearly distributed along the thickness of the plate, to which an additional internal stress is calculated according to Timoshenko’s theory. Finally, the temperature warping stress of double-layer concrete pavement is obtained when the temperature is curvilinearly distributed along the thickness.
