MODELLING AND CALCULATION OF THE REINFORCED BASIS FROM GRANULAR MATERIALS
The calculation model of the granular layer reinforced with geogrid is submitted as the two-layer plate with rigidly connected layers on the elastic basis. The lower layer models a geogrid. It is presented by a uniform composite ortotropic layer with physicomechanical characteristics significantly different from characteristics of an overlying layer. The basis layer under the reinforced plate is replaced like the coefficient of the bed. Calculation of a multilayered plate on the elastic basis is executed by Bubnov-Galerkina's method. Satisfactory coincidence of calculations results to results of stamp tests of the basis from the crushed stone layer reinforced by geogrid with steel fibers in a polyethylene cover is received.
