摘要
为考察旧水泥混凝土路面加铺沥青混凝土层时,设置夹层对旧水泥混凝土板应力的影响,结合G 104徐州机场路改造工程,利用AN SY S三维有限元计算工具,对比分析了单夹层及复合夹层结构中旧水泥混凝土板荷载应力变化规律。结果表明,两种夹层设置方式对水泥混凝土板荷载应力影响规律几乎相同。
In order to research the influence of interlayer on old cement concrete slab with asphalt pavement up-layer, taking restoration engineering of the G104 Airport Expressway in Xuzhou City for an example, with the help of 3D FEM ANYSY, the impact law of single interlayer and composite interlayer on stress of old cement concrete slab is analyzed by contrast. The results show that the set modes of two different interlayers have the almost same influence law on stress of old cement concrete slab.
