Numerical evaluation for protecting and reinforcing effect of a new designed crushed rock revetment on Qinghai–Tibet Railway

Crushed rock revetment (CRR) has been widely implemented to mitigate the geothermal disturbance from the embankment construction and global warming. The cooling effect and air convective mode of the traditional CRR (TCRR) and a new designed solar−shading CRR (SSCRR) were comparatively studied based on a developed and verified heat and mass transfer model. The results indicate that TCRR used as a protecting measure cannot eliminate the geothermal...
