对水泥砼路面伸缩缝传力效率的探讨

通过缩缝处荷载传递机理及方式的分析与探讨 ,认为在轻、中交通情况下 ,缝面上集料颗粒咬合作用加半刚性基层足以传力 ,其传荷能力与传力杆传荷能力相近 ,并建议采用板中临界荷载确定砼板厚 ,可减薄路面面层厚度 1～ 2cm。

On Load Transfer Efficiency of Contraction Joints in Cement Concrete Pavement

Analysis of the mechanism of load transfer at the contraction joint shows that clutching of particles on the surface of the joint with the semi rigid base is sufficient for load transfer under light and medium traffic, similar to the capacity of the dowel. It is proposed that the thickness of concrete plate be determined using the critical load in the plate so that the facing thickness may be reduced by 1～2cm.
