摘　　要：贝克曼梁法检测水泥混凝土路面板底脱空是国内外广泛使用的方法,也是我国水泥混凝土路面路面强度调查的主要方法,水泥混凝土路面有很多接缝,在长期行车作用及雨水渗入作用下,很容易造成板底脱空。本文根据贝克曼梁法检测的弯沉数据,在综合考虑路面板块承载能力、传荷能力的情况对板块提出了处理方案,并进行了实例验证。Backman beam method for detection of the cement concrete pavement is widely used at home and abroad, and it is the main method of cement concrete pavement strength of our survey, there are a lot of the joint of cement concrete pavement, in the long-term running effect and infiltration of rainwater effect, very easy to cause the void beneath slab. According to the Backman beam method detection deflection data, this paper proposes treatment scheme on the plate considering the road block bearing capacity, load transfer capability, and verifies.

关 键 词：水泥混凝土路面 弯沉 承载能力 传荷能力 板底脱空
