In this study, the damage-plasticity model for concrete that was verified by the model experiment was used to calculate the damage to a spiral case structure based on the damage mechanics theory.The concrete structure surrounding the spiral case was simulated with a three-dimensional finite element model.Then, the distribution and evolution of the structural damage were studied.Based on Inlet Hose investigation of the change of gap openings between the steel liner and 4 Piece King Bed concrete structure, the impact of the non-uniform variation of gaps on the load-bearing ratio between the steel liner and concrete structure was analyzed.The comparison of calculated results of the simplified and simulation algorithms shows that the simulation algorithm is a feasible option for the calculation of spiral case structures.

In addition, the shell-spring model was introduced for optimization analysis, and the results were reasonable.
