水泥混凝土路面板底脱空弯沉判别方法

Deflection Determining Method for the Void beneath Cement Concrete Pavement Slab

针对目前水泥混凝土路面板底脱空弯沉判别方法仅依靠单一弯沉值的情况,在系统分析基于静弯沉的单一弯沉值法和基于动弯沉的弯沉盆变异法、夹角法、弯沉比法等路面板底脱空弯沉判别方法基本原理的基础上,根据徐州地区某水泥路改造中试验数据,提出利用弯沉盆3步法进行水泥板脱空评定的科学方法,为综合利用路面板底脱空弯沉判别方法,提供依据。

In the view that there are many deflection determining methods for detecting the void beneath cement concrete pavement slab at present,and based on the basic principle of the static deflection determining methods such as the single deflection value method and the deflection difference between the corner of adjacent slabs,and the 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 are analyzed systematically,the fault and deficiency of these methods are pointed out. The further study of deflection determining methods for detecting the void beneath cement concrete pavement slab has clear direction.
