摘要:
为研究沥青路面在单圆和双圆荷载作用下的受力及变形的异同,验证用单元均布荷载等效双圆均布荷载的有效性.首先分析了双圆均布荷载下沥青路面弯沉及受力性能变化情况,然后分别进行了弹性层状理论下单圆和双圆作用下沥青路面受力性能对比研究及单圆和双圆动力加载作用下沥青路面力学性能对比数值模拟研究.结果表明:在动、静加载模式下,沥青路面在单、双圆均布荷载作用下的弯沉及应力除在路表处存在一定的差异外,随路面结构深度的增加,弯沉及应力变化趋势和大小均趋于一致,表明用单圆均布荷载等效双圆均布荷载进行设计及相关检测是可行有效的.
Abstract:
To study the similarities and differences of force and deformation of asphalt pavement under single roundand two round loads, and to verify the effectiveness of using single round uniformly distributed load equivalent two.round uniformly distributed load. Firstly , the deflection and stress of asphalt pavement under two-round uniform dis.tributed load were studied, and then the comparative stress analysis of asphalt pavement under single round and tworound loads based on elastic layer theory and numerical simulation study by dynamic loading of double-and singleround were carried out. The results show that: both in the statie and dynamic load mode, except some differencesexisting in the road surface, with the increase in the depth of the pavement structure, deflection and stress trendsand size are consistent for single round and two round loads, which means that with a single round uniformly distrib.uted load equivalent to two-round to design and testing is feasible and effective.
