Basal heave stability of excavations with JGP is investigated using finite element analysis. Comparison of the factor of safety using conventional methods and finite element analysis Modified Terzaghi method is proposed for assessing basal heave stability with JGP. Probabilistic analysis can be conducted through spreadsheet model. Charts for checking basal heave stability for preliminary design use
