Dynamics of the infiltration of liquid pollution into the ballast section of a railway track within the framework of Forchheimer’s law

Summary

The dynamics of a liquid layer infiltration into porous soil induced by the gravitational forces is considered within the framework of the two-term filtration law (Forchheimer’s filtration law). Simple formulas are obtained for the time dependence of the height of the liquid layer on the soil and the time of complete infiltration of liquid into the soil on the filtration coefficient and porosity of the soil. It is shown that the total infiltration time is directly proportional to the height of the initial liquid layer on the ground. Calculations of the time and average speed of complete infiltration for typical soils were carried out.
