The invention provides a statics analysis model correction method. The statics analysis model correction method comprises the steps of obtaining destruction boundary experiment data of a to-be-testedthermal protection structure; correcting the statics analysis model built based on the destruction boundary experiment data, and obtaining a statics analysis model within the margin of error. According to the technical scheme, the statics analysis model of a seaming interlayer integrated thermal protection structure is corrected by using experimental results, the precision of the model is improved, and the method is more real; further, the static strength safety margin of the seaming interlayer integrated thermal protection structure is assessed by the corrected model, and the assessment reliability is improved.
