Research of the stress state of reinforced foundation pads using model stamp tests






The article presents the results of model stamp tests on the study of the nature of two types of reinforced foundation pads under load. The tests were performed using a special tray with artificially prepared soft clay base. The key results of the research are experimental plots of "sediment-pressure" dependence for all types of tests, as well as the establishment of qualitative dependences of the stress distribution in the soil with the help of the array of soil pressure cells. According to the results of the model stamp tests, there was selected a reinforced foundation pad with a reinforcing element ("geogrid") to be used for further studies.
