Abstract:Under the background of the express-reconstruction of the Qinghai-Tibet Highway being proposed, it will be necessary to employ the special technique of cooling the ground temperature by the crushed rock embankment in order to protect from damage to highway embankment due to thaw settlement. Under vibrating load, the porosity variation of crushed rock layer may weaken the cooling effect of buoyancy-driven natural convection of the pore air in the crushed rock layer of the highway embankment, thus resulting in i… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
