Article Preview

For cement-soil pile composite subgrade under rigid foundation, a three-dimensional nonlinear finite element analysis is performed to analyse critical length-diameter ratio based on deformation, which is first introduced, according to replacement ratio, pile-soil modulus ratio and the modulus ratio of substratum and reinforced area. It is found that critical length-diameter ratio of cement-soil pile under rigid foundation mainly depends on replacement ratio, the impact of pile-soil modulus ratio and the modulus ratio of substratum and reinforced area is relatively little.
