摘要
将振动压路机对被压实层施加的作用力简化为圆形均布荷载 ,利用弹性层状体系理论 ,对基层振动压实作用下的底基层压应力和拉应力进行了计算分析。结果表明 ,对基层进行振动压实时存在着半刚性底基层发生弯拉强度破坏的可能。
The pressure of vibrating roller on the compacted course was simplified as cylindrical uniform load. Using elastic multilayer theory, the compressive stress and tensile stress of the subbase course by vibrating compaction are calculated and analyzed. The results show that there is damage possibility of semi rigid subbase in bending strength when vibrating compaction conducted on the base course.
