Using reinforced bases in clay soils is studied still insufficiently well. Therefore, in order to use the building practice of constructions of the bases on the reinforced ground it is necessary to carry out the analysis of their is stress-deformed condition to reveal a rational scope and to develop optimum constructions of the reinforced bases. For studying of work of the reinforced bases complex theoretical experimental researches have been carried out: laboratory modelling researches, natural tests, numerical modelling of work of the reinforced bases in water sated clay soils. The tests revealed that the single layer reinforcing clay base results in an increase in bearing capacity of 1.35 times the base. Effectiveness of reinforced bases increases with increasing precipitation structures. Stress-strain state reinforced base is markedly different from the stress-strain state of reinforced base. Introduction reinforcing element transforms the stress distribution in the core base. Stresses concentrate in an area of the reinforcing layer and decrease in the area below it. Redistribution of the active area in the vertical stress is reinforced based on depth amount 1.0-1.25 d from the base of the stamp, and in width by up to 1.0 d from the axis of the die. The test results showed high efficiency of reinforcement to increase the bearing capacity of foundations in clay soils. The carried out researches have allowed to receive a qualitative and quantitative picture of reinforced soil work of the bases and their stress-deformed condition to define a rational scope and to develop recommendations or their designing.
