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.

为减轻堤防的沉降，常采用水泥土加固软基的方法。本文通过单剪试验和有限元分析，研究了网格状水泥改良砂土的力学性能和破坏模式。通过一系列不排水三轴压缩试验，研究了养护压力对水泥土强度的影响。
