This invention proposes a method for calculating the damage range of a ground-impact nuclear explosion. The method includes decomposing the nuclear explosion energy into four main components: shock wave energy flux, thermal radiation energy flux, seismic wave energy flux, and electromagnetic pulse energy flux. A heterogeneous medium model is constructed, incorporating atmospheric and geological models. Topographic and geological data are integrated to generate a joint map describing the spatial correlation between topography and strata. Nonlinear wave equations and a dynamic atmospheric transmittance model are used to calculate shock wave and thermal radiation propagation, and to assess the impact of seismic waves and electromagnetic pulses. A fuzzy logic algorithm is used to establish a damage probability mapping relationship, plotting a nuclear explosion damage range map, and dynamically updating it through a Bayesian learning module. Through multi-physics field coupling analysis and a dynamic learning mechanism, the invention improves the accuracy of nuclear explosion damage assessment.
