Dynamic Response Analysis of Compaction Loess Subgrade

Abstract:

The problems of compacted loess roadbed utilization are closely related to the characteristics of compacted loess and long-term vehicle loads. According to the characteristics of compacted loess in different degree of compaction, the distribution and deformation change rules of the dynamic stress under dynamic load are studied through the finite element program numerical analysis of vehicle loads roadbed dynamic response. The data is acquired by field test and laboratory experiment. In lighting of the influence of the subgrade deformation by degree of compaction and pavement structures, the influence models are given which are used for estimating the roadbed vertical displacement in different conditions.
