Abstract:There exists such defects as the displacement layer being more thick, the puddle backfill quality being un-easily ensured and the project cost being higher while sandy gravel material is used to displace the foundation soil in order to prevent the freezing damage. The polystyrene foam plastic slab, as a new type of heat insulating and frost preventing material, has such advantages as the thickness and dead weight being small, and the frost preventing performance being well, and has the higher value of application and popularization.
Keywords:canal  frost heaving prevention  polystyrene foam plastic slab
