The invention belongs to the technical field of simulation calculation, and particularly relates to a method for analyzing gas-solid interaction in a containment in a containment integral pressure test. Comprising the following steps: step 1, selecting a computational fluid dynamics and solid domain stress analysis software platform, and proposing hardware configuration requirements for a computer adopted for analysis; 2, establishing geometric simulation models of a fluid domain and a solid domain; 3, performing grid division on the fluid computational domain and the solid domain; 4, defining fluid domain calculation boundary conditions; 5, selecting a turbulence model; 6, determining a residual convergence criterion and calculating a time step length; step 7, carrying out transient nonlinear solution by adopting an implicit solver; and step 8, processing a calculation result. The method has the beneficial effects that (1) by establishing a high-fidelity simulation analysis model for the physical state of th
