Abstract

Based on the design proposal on the reconstruction of the Da Wei Jian Cai road section between the 107 National Highway and Songfeng Road in Hengyang, Analysis on mechanics response of the related pavement structure layer concerning the two different models established here through the Finite Element Analysis Software ABAQUS. The two different models are conceived according to whether the bottom of the new concrete base above the splicing seam-line on the new and old pavements buries steels. The results show that compared with the purely-simple concrete splicing, the new steel-burying concrete base above the splicing seam-line makes a striking decrease both in the maximum longitudinal tensile stress between layers and the vertical subsidence displacement at the bottom of the base. Besides, the adoption of steels in splicing seam-line can effectively separate the mechanics response and guarantee the load transfer between the longitudinal seam-lines, which to a certain extent, can effectively prevent the longitudinal seam from cracking.
