Method of Void Identification Beneath Concrete Slabs Based on Beckelman Beam Deflection Value;
基于贝克曼梁弯沉值的板底脱空判别方法
In the paper based on the deflection at the transverse joint and the center of slabs measured with Beckelman Beam,the method of void identification is established by comparing the back-calculated Winkeler foundation reaction modulus at the edge of transverse joint and the center of slabs.
为满足目前水泥混凝土路面养护的需要,本文探索用贝克曼梁检测混凝土板横缝处和板中弯沉,应用Winkeler地基板的弯沉与荷载关系式,反算板中和板边处地基反应模量,通过对比该模量判定混凝土板底是否脱空。
