Calculation model of foundation base settlement at the static and cyclic regime loading

摘要

The article presents results of experimental and theoretical researches of the clay ground basesrnsoils under triaxial long-static, cyclic and regime static-cyclic loading. Described the source and transformed thernclay ground deformation diagrams for long-static, cyclic-static and modal prolonged cyclic loading. Test resultsrnare presented and processed in the form of graphs and used for comparison with theoretical studies. Based on thernanalysis of the transformed strain diagrams developed engineering method for calculating ground settlement,rnbased on the method of layering summation taking into account spatial changes of stress – strain state of thernground in the process of regime static and cyclic loading. At the end of the article compares the results of triaxialrnwith a trough tests at long-static, cyclic and static and modal prolonged cyclic defor-mation of the clay base raftrnfoundation.
