TSTU publisher house , 2016. (pdf-file) Abstract: The results of experimental studies of reinforced sandy slope stability under the action of vertical surcharge are presented in the article. There have been made a few series of experiments in which the depth of the reinforcing element, as well as the parameters of reloading – cyclical (5, 10 and 20 load cycles) and
static one – were varied. The case of the presence of the weak soil
interlayer situated at different depths within the slope is discussed.
The dependences of the influencing parameters on the displacements and limit pressures under the pilot stamp foundationbed have been obtained. It is shown that fabric-reinforced slope can bear vertical load almost two times greater than a non-reinforced one, with smaller deformations. Absolute values of the breaking load after cycling are greater than those at static loads. It is found that the use of reinforcement eliminates the possibility of the landslide collapse of the slope and the location of the weak soil interlayer at a depth greater than the diameter of the model has almost no effect on the slope bearing capacity and makes the reinforcement in this area ineffective.
