| 摘 要： | 针对车辆荷载对山西高速公路路基土体影响研究不足的现状,从试验角度出发,研究车辆荷载水平、波形、干密度和围压对路基土体的动力特性响应。研究表明:路基土体的体变随波形比的增大而增大,随车辆荷载的增大而增大;路基土体的动弹性模量随干密度的增大而增大,随围压的增大而增大,阻尼比随围压的增大而减小。

| Abstract: | To determine the effects of vehicle load on the soil mass of an expressway subgrade soil in Shanxi Province, we investigated the dynamic response from vehicle loads, the seismic waveforms, and the soil dry density and confining pressures. The results show that the volume deformation of the subgrade soil increased with an increase in waveform ratio and vehicle load, the dynamic elastic modulus increased with an increase in dry density and confining pressure, and the damping ratio decreased with an increase in confining pressure. |
