通过采用有限元分析软件ANSYS建模,计算水泥混凝土路面在脱空状态下的最大弯拉应力,并考虑板块厚度、脱空深度、脱空范围等因素对水泥混凝土路面的最大弯拉应力的力学响应,结合计算结果分析脱空状态对水泥混凝土路面疲劳寿命影响.%An ANSYS model is adopted to calculate the maximum stretch stress of concrete pavement with void under slab considering the effect of slab thickness, void depth and area under slab, the result is used to analyse the fatigue life of concrete pavement with void under slab.
