水泥混凝土隔离式盖被道面板动力学试验研究

摘要

The dynamics tests of cement concrete isolated cover pavement were carried out by runway test-bed. The pavement loads were analyzed under different thickness of isolated layer, different thickness of cover layer, different thickness of old runway and different wheel speed. And influence laws of the four factors on pavement were discussed. The results show that the thickness of isolated layer and thickness of cover layer are more important impact on pavement loads, and ideal thicknesses of isolated layer and cover layer are 1.0mm and 21mm respectively.%利用跑道试验台对水泥混凝土隔离式盖被道面板进行了动力学试验研究，分析了不同的隔离层厚度、盖被层厚度、旧道面厚度以及不同机轮速度条件下，道面板所受荷载的情况，探讨了这四种因素对道面板的影响规律。结果表明，隔离层厚度、盖被层厚度对新旧道面板所受荷载影响较大，较理想的隔离层厚度和盖被层厚度分别为1.0mm、21mm。
