| Research Abstract |
To mitigate liquefaction-induced settlement of levees, improvement of liquefiable foundation ground by cement is often adopted. In this study, mechanical properties and failure mode of sand improved by cement in grid pattern were examined by simple shear tests and finite element analysis. Effects of curing pressure on strength of the cement-treated sand were also examined by a series of undrained triaxial compression tests.
