We invite you to watch the video tutorial on calculation of filtration in soils, namely, the determination of seepage velocity, pore pressure, stresses and positions of phreatic surfaces. Such calculations are made for dams, pits, underground tunnels, drain shafts, etc. The video shows the features of the construction and calculation of a nonhomogeneous dam with drainage systems in a plane problem, as well as modeling of filtration processes for a homogeneous dam in 3D setting. The video is recorded in Ukrainian.
