Baryshpol A. The project methods for drainage sistems of airfield coverings

The dissertation is devoted to development of methods of account of time of drainage of drainage layers of airfield water-permeable coverings, in view of process of a nonstationary filtration of drainage waters. On the basis of theoretical and experimental researches the technique of hydraulic account of four types of water-permeable coverings is developed. The basic dependencies of time of drainage of drainage layers on factor of a filtration of a material of a drainage, thickness of a drainage layer and hydraulic gradient are established, the received results are checked up by experiment. The recommendations for practical application of water-permeable coverings are developed.
