Numerical simulation of stress path tests on sand

More Information
  • Published Date: January 14, 2008
  • Based on a set of stress path tests,numerical simulation of the deformation behavior of saturated sand in triaxial consolidation and drained tests under different stress paths was carried out by use of the state-dependent sand model.The results of numerical simulation were discussed.Compared with the test results,the model simulation broadly matched the test results under different stress paths in terms of both the shear stress-strain response and volumetric characteristics.Generally speaking,the above model could reflect most of the deformation behavior of sand except some limitations on the volumetric change process under triaxial extension path,and it should be further studied and improved.
