Military geology is mainly oriented to the exploration and research of complex geological environment in typical scenes. Modern high-tech warfare puts forward higher requirements for military geological informatization and refinement. The application of modern engineering geological analysis methods to military geological application research is increasingly important for the development of military geological technology. On the basis of summarizing the traditional research methods of engineering geology, this paper discusses the typical cases of engineering geological analysis methods in military geological application research. The research shows that the natural history analysis method, as an effective method for military geological application research, can play an active role in military applications such as military transformation of civil geological data, assessment of mobile traffic capacity, assessment of fortification stability and resistance to strike, and risk assessment of key geological disasters. The application characteristics of multidisciplinary cooperation in modern military geology determine a new way for the integration and development of modern engineering geological analysis methods and other geoscience research ideas and methods, which may become an important ability to promote military geology to solve practical military problems.
