The model is implemented through a user defined material model in LS-DYNA. The model parameters are calibrated and validated by the data from related concrete penetrationtests.
The theoretic instructions for some geotechnical engineering problems in unsaturated soil areas could be provided, such as the penetration of piles, cone penetrationtests, etc.
其结论可为非饱和土地区的沉桩、静力触探等岩土工程问题提供理论依据。

By comparing the results of in-situ TBM penetrationtests with the prediction penetration rates, the applicability and errors of these penetration rate prediction models were discussed.
