Initial geo-stress is an important factor in geo-technical engineering numerical simulation and how to balance initial geo-stress in ABAQUS finite element software is the key to ensuring the validity of numerical calculation results. According to four kinds of different initial geo-stress balance methods provided by ABAQUS, this paper separately uses examples to verify the practicability, advantages and disadvantages of each method to conduct initial geo-stress balance and analysis results show that, as for simple geo-technical, the auto-balance method, keywords initial geo-stress definition method, ODB import method and initial geo-stress extraction method provided by ABAQUS can achieve the balance effect, however, with regard to geo-technical of complex geo-conditions, only auto-balance method and initial geo-stress extraction method can obtain better balance effect. The research conclusion can present reference for numerical calculation of complicated geo-technical.
