摘要:
交通荷载作用下斜坡加筋路堤稳定性和变形特性一直是人们普遍关注的问题.采用数值模拟方法,在路堤顶面施加均布循环荷载,分析了交通荷载作用下路堤的动力特性.最后,对交通循环荷载的振幅、频率以及行车间隔进行参数分析.结果表明:交通荷载作用下,路堤顶面沉降随着循环次数的增加而增大,但增大的幅度逐渐变小,直至趋于稳定;交通荷载振幅、频率越大,行车间隔越短,路堤顶面最终沉降越大.
Abstract:
The deformation characteristics and overall stability of high embankment under traffic load havebeen widely studied in recent years. Based on numerical simulation method ，the response of embankment un-der dynamic uniform loads acting on the embankment surface is studied. Finally , the impacts of traffic loads’amplitude，frequency and running interval on the embankment response are analyzed. According to the re-sults , the settlements of embankment surface under dynamic traffic loads grow with the cycle index, but the in-crease percentage of deformation diminishes gradually to a stable value. The maximum settlement of embank-ment surface increases with the increment of traffic load’ s amplitude,frequency and the decrement of runninginterval.
