description | Practice shows that the foundations of buildings located on a sandy base and transmitting dynamic loads to it receive undamped settlement, causing damage to structures and even the collapse of buildings, which best shows the relevance of the affected problem. The purpose of this work is to study and improve methods for quantifying the stress-strain state of sandy foundations operated under the influence of dynamic loads, taking into account the vibration creep of sandy soil. The authors conducted a laboratory study of the vibration creep of sandy soil under vibration on an experimental design of a soil dynamic ball viscometer and an analytical solution to the problem of foundation settlement under dynamic load. According to the results of laboratory studies, the authors have identified the relationship between the value of the viscosity coefficient η0 and the intensity of tangential τi and mean stresses σm, which is later used in analytical calculation. Taking into account the propagation of static stresses according to the dependencies of Kolosov G.V., the propagation of vibrations in plan and depth according to the dependencies of Savinov O.A., the change in the viscosity coefficient depending on the intensity of vibration acceleration according to Barkan D.D., Ter-Martirosyan A.Z., Sobolev E.S., a quantitative assessment of the settlement of the base was carried out. The dependences obtained by the analytical method are consistent with the tray and field results of early studies by other authors. |
