| 摘 要： | 为掌握路基动态模量与静态回弹模量之间的关系,应用便携式落锤弯沉仪(PFWD)与承载板法,对填料为碎石土、黏性土和红砂岩的路基动态、静态模量进行对比试验以及相关回归分析。结果表明:路基动态模量和静态回弹模量之间存在着良好的相关性,PFWD这一新型检测法可较好地用于路基回弹模量的快速检测和评价。

| Abstract: | In order to master the relationship between subgrade dynamic modulus and static modulus of resilience,comparative test and related regression analysis shall be carried out for dynamic modulus and static modulus of subgrade separately filled with gravel soil,clay and red sandstone using portable falling weight deflectometer(PFWD) and bearing plate.The result shows that there is good correlation between subgrade dynamic modulus and static modulus of resilience.PFWD such new method can be better applied in rap... |
