Structural Background of Geda Area in Tibet and Its Influence on Exercise and Training Activities

Tectonic geology is one of the most critical factors affecting geological activities in the regional geological background. By studying the structural geological environment of Geda Township and analyzing its geological units and tectonic stresses, it is concluded that: (1) Six large faults developed in the area in the near-north-south direction control the basic geological and tectonic structure of the working area and affect the spatial structure of the area; The depression of the fault is the Geda fault depression basin, and the flat valley area of the basin is relatively flat, which is conducive to the assembly and cantonment of troops. (2) The extension scale of the fault system extends a large scale, the direction of nearly north-south, in the engineering layout or field mobility, and the fault zone should be avoided as much as possible in engineering layout or field maneuvering; (3) There are many valleys, gullies and other connected landforms in the area, which are conducive to the passage of troops and logistics supplies; (4) The tectonic pattern of Geda sedimentary basin formed by the near-north-south oriented Geda sedimentary basin basin-control rupture system provides a good channel for field maneuvering; (5) The north-south fault system leads to the development of cracks and good penetration in the area, and the groundwater penetrates the surface well due to various effects such as pressure or siphon, and the entire water supply system in the area is guaranteed. Based on the combination of structural geology and military geology, this study preliminarily reviews the relationship between the two, and provides ideas for the integration of the two professional disciplines.
