Abstract：Based on complex variable differentiation method and according to the basic principles of the elasto- viscoplastic finite element analysis，Newton-Laplason iterative Optimized method is adopted with back analysis parameters and elastico-viscoplastic displacement by programme Fortran. With displacement of the key monitoring points，both strength parameters and creep parameters are back analyzed efficiently and accurately. Two examples verified the method¢s feasibility.
