Investigation of dynamic response of the underground oil storage facility subjected to explosion loads is an important problem. The oil tank can be predigested as a flat-closure cylindrical shell structure. Considering the stress characteres of underground cylindrical shells, the amendatory Winkler model was used to simulate the interaction between cylindrical shell and soil, and a method to determine the related parameters was presented. With the explosion simulation device, a model experiment of underground steel cylindrical shell under explosion loads was completed. An appropriately simplified model of the peripheral explosion loads distribution of the cylindrical shell was assigned according to experimental results. Finete element analysis for the dynamic buckling of flat-closure cylindrical shell was carried out and the critical buckling loads were determined by Budiansky-Roth criterion. Relastionship between critical buckling loads and soil elastic constant K was determined according to the multi-state computation results.
