摘　　要：针对板底脱空极易导致水泥混凝土路面板的断裂和破碎,并严重影响水泥混凝土路面板使用性能和疲劳寿命的情况,以烟台-威海高速路试验段为依托工程,将水泥路面板和板底脱空部分作为统一的力学分析体系,采用三维有限元软件对存在板底脱空的水泥路面结构进行了模拟,并对温度和轴载耦合作用下路面板的等效应力、最大剪应力及弯沉进行了计算,分析了不同降温幅度对路面板力学状态的影响,研究了存在板底脱空的水泥路面板的力学特性和弯沉变化规律。In view of the situation that void beneath concrete slab accounted for fracture and crushing of cement concrete pavement,in addition,it seriously affected pavement performance and fatigue life of cement concrete pavement,taking Yantai-Weihai expressway for example,cement concrete pavement and slab part were seen as a whole for mechanical simulation and analysis.By ANSYS,some pavements were simulated;moreover,equivalent stress,maximum shear stress and deflection were calculated under the combined action of temperature and axis＇s load. According to the calculated results, the paper analyzed the impacts of different temperature drop range on pavement, the mechanical properties of cement concrete pavement with slab and variation of deflection.
