Statement of the problem. The problems of searching for an accelerated solution of the problem of calculating the parameters of drainage systems are studied by means of mathematical modeling of water transfer in a porous subbase of a road.Results. Based on an exact solution of a humidity ure transport equation in porous soils, a technique for investigating vertical filtration has been developed. It is shown that the rate of a rise in water levels along the height of the soil layer is unstable and changes as a maximum value of the height of a subbase is reached.Conclusions. The technique sufficiently describes the transfer of humidity ure in a porous soil and is useful for accelerated analysis of the parameters of drainage systems in the subbase of a road. An example of the application of the procedure is given for a new scheme of water removal from under the roadway, which reduces the negative effects of frost heaving.
