Outline of Final Research Achievements |
Tensile stress possibly occurs in cement mixing soil column and wall under a low confining stress condition when external forces apply to the column or wall. Thus the evaluation of tensile behavior of cement-treated soils is one of the major issues for designing the ground improvement. The purpose of this study is to clarify the tensile and shear failure criteria of cement-treated soil. Triaxail tension tests are conducted to reveal the tensile and shear failure behaviors of cement-treated soils. Moreover the elasto-plastic model developed by the researcher is verified by comparing between the experimental and numerical results. The developed elasto-plastic model can be implemented in the finite element software DIANA.
