Abstract
The article deals with the ensuring reliable protection of underground buildings and structures from groundwater influence. The analysis of existing methods and materials used in wall drainage systems is carried out. In order to improve the quality of construction and operation of underground structures, filtering drainage slabs made of polystyrene foam are proposed. To develop the design of slabs with longitudinal holes that increase their water permeability, the method of electro hydrodynamic analogies was used. Deformations of filtering slabs with holes with a diameter of 4 cm under the action of compressive loads exerted by backfill soil were investigated. Dependence of the compressive strength and water permeability of filtering slabs upon short-term (compressibility 10%) and long-term (compressibility 2%) loads is presented. Based on the results of the experiment, it is found that the obtained material has high filtration characteristics with sufficient strength and can be recommended for the protection of underground structures with a depth of up to 10 m.
