水泥路面板底脱空的弯沉判别方法

针对目前水泥混凝土路面板底脱空弯沉判别方法繁多的情况,在系统分析基于静弯沉的单一弯沉值法和相邻板角弯沉差法与基于动弯沉的截距法、弯沉盆变异法、夹角法、弯沉比法和模量反算法等现有路面板底脱空弯沉判别方法基本原理的基础上,分别指出了各种方法存在的不足和缺点,为路面板底脱空弯沉判别方法的进一步研究指明了方向.

Deflection Determining Method for Detecting Void Beneath Cement Concrete Pavement Slab

In the view that there are many deflection determining methods for detecting the void beneath cement concrete pavement slab at present, and based on systematic analysis of the basic principles of static deflection determining methods such as the single deflection value method and the deflection difference between the corner of adjacent slabs, and dynamic deflection determining methods such as the intercept method, the deflection basin variation method, the angle method, the deflection ratio method and the modulus back calculation method, fault and deficiency of these methods are pointed out, which gives the direction to further research of pavement deflection criterion methods.
