Abstract:
The decision of the waterpermeability nonlinear task during the incomplete watersaturation of the earth medium was submitted. The use of the integral substitution of Kirchhof type and the resulted quasilinearity of the moisture permeability equation was shown. The main relations of the final elements method were obtained. The developed technique allowed to solve the model problem on the moisture fields determination in the earth patlern of the traperoidal cross-section.
