为对水泥路面板的脱空情况检测评价方法进行优选,本文首先对目前常用的几种脱空检测方法进行了讨论分析,然后通过贝克曼梁实测路面板弯沉和钻芯取样对板边中点-板中弯沉差和板角-板中弯沉差两种判断方法进行了对比分析,结果表明:板边中点-板中弯沉差法更适宜作为水泥路面板的脱空检测评价方法。
In order to optimize the method of testing and evaluating the emptying condition of cement pavement slab, this paper first discusses some commonly used methods of void testing and then analyzes the deflection of slab and core sample by Beckerman beam Point-plate deflection difference and plate angle-plate deflection difference between the two judgment methods were compared, the results show that: the edge of the board - deflection method is more suitable as the board of the cement road surface void evaluation method.
