Abstract

In order to analyse the changing quality evaluation indexes in the compaction process of cement-stabilised gravel subgrade, and to analyse its change mechanism from the perspective of its calculation principle, the secondary development of Abaqus finite element analysis software was further carried out by writing USDFLD subroutine; at the same time, the experimental data of large-thickness water-stabilised layer compaction were brought into the finite element software analysis to realise the The data from the large-thickness water-stabilized layer compaction experiments were brought into the FEA software to analyze the dynamic changes in material parameters and strain changes during the cement-stabilized subgrade compaction process, effectively improving the accuracy of the numerical simulation results. This will provide a comprehensive understanding of the changes in the compaction of the subgrade during the vertical vibratory rolling process, which is of practical significance for the analysis of the subgrade rolling process and the reduction of damage caused by compaction testing.
