Creep Level Qualitative Evaluating of Crushed Rock
It is concluded that the creep level of the crushed rock is evaluated at Grade II, which is characterised by a low creep level of the rock and a small amount of deformation (0~10mm). The research results can provide a reference for the creep analysis of crushed rock and provide a basis for the safe construction of engineering slopes.

Thermo-mechanical stability analysis of cooling embankment with crushed
The crushed-rock layer is a porous media with highly permeability. Heat convection can occur within this layer. The heat convection of fluid inside crushed-rock layer is unsteady [10], [11], [14], [27]. The boundary of crushed-rock layer is air-impermeable, only the motion of interstitial air is considered, and it is assumed to be incompressible.
