  • Interval analysis method is a new uncertainty analysis method for engineering structures.A new sensitivity analysis method of engineering parameters was gained by introducing interval analysis method.And this will widen the application domain of interval analysis method.The interval analysis process of sensitivity factor matrix of soil parameters was given.The choosing method of the parameter intervals and decision-making target intervals was given according to interval analysis method.During the process of FEM,the secondary developments were done for Marc and the Duncan-Chang nonlinear elastic model and the mutual transfer between FORTRAN and MARC were implemented.By the engineering example,the rationality and feasibility were validated.And the conclusion was compared with that of the literatures.
