| 摘 要： | 针对目前不合理的土基回弹模量取值现状,通过对河南省南阳地区土基回弹模量和弯沉检测指标进行试验测定,得出该地区土基回弹模量分别与回弹弯沉、压实度和稠度之间的相关关系,最后论证地提出重型压实标准下该地区土基设计参数取值,反映了该地区实际取值水平,为公路设计提供科学依据.

| Abstract: | Considering the current status of unreasonably determining rebound modulus of subgrade,the relations between rebound modulus of subgrade and its rebound deflection,compactness and consistency are obtained by experimenting on the rebound modulus and rebound deflection of subgrade in Nanyang zone of Henan province.Finally,the values of subgrade parameters with heavy compaction standard are demonstratively proposed.The study conducted in this paper reflects the actual level and provides a scientific basis for highway designing of the region. |
