Title of the articleExperimental studies of basments’ models reinforced by horizontal grid under the cyclic loading
Abstract.To study the soil foundations, reinforced by horizontal polymer grids under cyclic loading tests in the laboratory were carried out. The article shows the results of experimental studies of models of soil basements, horizontal reinforced polymer grids such as the a40, on the effect of cyclic loading. Experimental tests have allowed establishing basic patterns of change in the stress-strain state grounds, reinforced by horizontal grids. Deformations of the soil and the elements of the horizontal reinforcement grids within the compressible thickness at the base increases under the cyclic loading. Deformities with varying intensity have evolved throughout the test. The most intensive development of ground deformations and horizontal grid reinforcement occurred at the initial stage of loading up to 200 ... 500 cycles. In the future there is a relative stabilization of these indicators. The action of cyclic loads is an increase in the horizontal grid reinforced base. In the initial stage of cyclic loading up to about 500 cycles, there is an intensive increase in sediment. With further development of the pellet loading rate is reduced, but complete stabilization occurs.The experimental results are presented in the form of graphs of settlement and strain on the number of load cycles. The basic laws of stress-strain state of reinforced horizontal array. Analysis of plots shows that the strain in the soil and in the horizontal reinforcement grids increases during cyclic loading.
Keywords.cyclic loading, horizontal reinforcement, settlements, stress, ground, deformation.
