Mechanism of suffusion removal of sand particles during vertical filtering

UDK: 624.131.432

Zh. Ju. Ponomareva, D.M. Dimuhametov Perm State National Research University, Perm, Russian Federation;

The methodology of experiments was aimed at creating the conditions suffusion of dip formation close to the actual processes developing in the areas of urban water-bearing defects communications. The experiments were carried out in laboratory equipment of the Department of engineering Geology and subsoil protection, Perm state University. The experiments of the physical laboratory modeling of the vertical filtering, a comparative analysis of the process at different capacity of the soil, the dependence between time, amount of removal and the relative deformation of the surface. For the investigated sandy soil, physical properties are determined-granulometric composition, density by the cutting ring method, angle of natural slope in the natural state and under water. Calculated an additional indicator suffusion takeaway – the value of the critical volume of soil that indicates the beginning of a process on the surface. The described sequence of the process of suffusion removal of fixed boundary conditions and symptoms-indicators.
