In relation to the foundation pit engineering of a metro station in soft soil region in Guangdong Province,the finite element software midas GTS was used to carry out numerical simulation and study the effects of different reinforcement forms on restriction of foundation pit deformation.The result shows that,there exist significant differences among the effects of different reinforcement forms on restriction of foundation pit deformation;under each reinforcement form,the restriction effect on foundation pit deformation is improved with the increment of reinforced area ratio,but not in linear relationship;when the reinforced area ratio reaches a certain value,the restriction effect is no longer improved;when the reinforced area is the same,strip reinforcement will contribute an optimal effect on restriction of foundation pit deformation.
