Vector type main shock and aftershock risk analysis model construction and early warning method and system

The invention provides a vector type main shock and aftershock risk analysis model construction and early warning method and system. The method comprises the following steps: establishing a main shock and aftershock database of a target engineering structure; acquiring at least one characteristic signal related to each main shock and aftershock from a main shock and aftershock database; performing data analysis on the target engineering structure by utilizing the characteristic signal to obtain each analysis result; all analysis results are combined and calculated, and a vector type main shock and aftershock vulnerability curved surface and a vector type main shock and aftershock risk curved surface are determined; and performing integral calculation on the vector type main shock and aftershock vulnerability curved surface and the vector type main shock and aftershock risk curved surface, and determining a vector type main shock and aftershock risk analysis model. The problem that aftershock events cannot be
