The criterion to judge the ultimate state of the scooted head pile bearing uplift load in soil foundation is insufficient at present. According to this problem, a numerical simulation method based on Failure Approach Index considering Mohr-Coulomb yield criterion is adopt to study a quantitative and sufficient criterion for the ultimate state of the scooted head pile bearing uplift load in soil foundation. A scooted head pile in homogenized soil foundation is taken as an example, the ultimate uplift load of the pile is obtained by test, at the same time the ultimate uplift load of the pile is obtained by numerical simulation method based on Failure Approach Index considering Mohr-Coulomb yield criterion. The research results indicate that the two values of ultimate uplift load of the pile obtained by test and the numerical simulation method are very close, which give the sufficient evidence that the criterion for the ultimate state of the scooted head pile bearing uplift load in soil foundation based on Failure Approach Index is sufficient and reasonable.
