| Abstract: | This paper puts forward the coupling model of the heat-moisture-stress field based on the governing equation of
non-stationary heat transfer, moisture movement and the basic differential equations of deformation problem by displacement
under axisymmetric conditions. Using a detailed calculation example for the section of the Xiang Pi Mountain
in 109th National Highway, a mechanical model of the cylinder made by typical silty clay soil is simulated. Results show
that in the coupling process, dynamic stress pays little contribution to the distribution of temperature field along different
depths, and the amount of thawing deformation increased with dynamic loading time under the same frequency and
amplitude. |
