摘要
为研究雄黄高速不同等级、不同改良深度盐渍土路基下的沥青路面结构层力学响应特征,文章采用了相似比尺与仿真模型计算的方法,对沥青路面结构层的应力、位移展开分析.研究表明,公路等级不同,但断面应力、Z向位移变化均会保持一致性;公路等级越高,沥青结构层应力波动性、位移变化均会越小.盐渍土路基改良深度对应力响应变化影响较小.
Abstract
In order to study the mechanical response characteristics of asphalt pavement structure layer under saline soil subgrade with different grades and different improvement depths on Xiongan-huanghua Expressway,this paper adopts the methods of similar scale and simulation model calculation to analyze the stress and displacement of asphalt pavement structure layer.The research shows that the highway grades are different,but the changes of section stress and Z-direction displacement will remain consistent;the higher the highway grade is,the smaller the stress fluctuation and displacement change of the asphalt structure layer are.The improvement depth of saline soil subgrade has little influence on the change of stress response.
