摘　　要：根据试验路几种脱空检测方法的结果,研究了水泥混凝土路面板脱空的弯沉判据,提出了以一定保证率下板角弯沉值与板角弯沉差作为路面板板角脱空的弯沉判据,为施工单位提供了一种简单实用的方法识别脱空板。The deflection criterion of the void under slab of the cement concrete pavement is studied on the basis of the results of several void detective methods in the experimental road. The deflection criterion for determining the slabs with voids is put forward by the slab corner deflection together with the difference of the slab corner deflection under certain assurance rate, which provides a simple and practical method to determine the presence of voids under concrete pavement slabs for the contractors.
