水泥混凝土路面板底脱空判别方法研究

Research on Determining Whether the Cavity Beneath Cement Concrete Slabs Occurred

根据弹性地基板计算的近似梁法，经过计算与分析，给出了采用板中弯沉值与板边弯沉值之比判断板底脱空现象的方法，并通过实例进行了验证。

Based on the analysis of plate above the elastic subgrade using approximate beam method, the relation between the deflection in the slab center and the deflection at the slab edge is established to appraise the cavity possibility beneath road slabs. The method presented in the paper is also verified through test road data.
