| 摘 要： | 针对交通荷载长期作用下高填方路堤的工后蠕变沉降问题,基于车辆交通荷载的特性分析,将路堤填筑体上产生的应力考虑成动静组合应力,建立了填筑体动静组合荷载下的Kelvin体蠕变方程,并将荷载参数对计算模型的影响进行了分析,结果表明:组合荷载下填筑体的蠕变与静载条件下蠕变有相同的时间变化趋势,与相同静载(与组合荷载最大应力相等...

| Abstract: | Based on the study of the behavior of high fill embankment,the stress in subsidence on high embankment was simplified into combined stress,and the creep settlement model of high-filled embankment after construction was established.By solving the differential equation of the Kelvin model under cyclic load,the creep equation was established,and the influences of the load parameters on the calculation model discussed.The facts show that the creep trend of Kelvin model under cyclic load is the same as that unde... |
