西藏格达乡构造背景及对演训活动的影响评述
Structural Background of Geda Area in Tibet and Its Influence on Exercise and Training Activities
摘要

构造地质在区域地质背景中, 是影响地质活动最关键的要素之一; 论文通过研究格达乡地区构造地质环境, 分析其内地质单元及构造应力等, 得出: ①区内发育6条近南北向的大型断裂控制了工作区基本地质构造格架, 并影响区内空间结构; 断裂中凹地为格达断陷盆地, 盆地平谷区域地势较为平坦, 有利于部队的集结和扎营; ②断裂系统延伸规模较大, 走向近南北向, 在工程布设或野战机动中, 尽可能地避免断裂带区域; ③区内多山谷、冲沟地貌等连通导向, 有利于部队通行及后勤补给; ④近南北向格达沉积盆地控盆断裂系统构成的区内构造格局为野战机动提供了良好通道; ⑤南北向断裂体系致使区内裂隙发育、贯通性好, 地下水由于承压或虹吸等多种作用, 较好的贯通地表, 整个区内供水系统得到保障。本次研究基于构造地质与军事地质相结合, 初步评述研判两者关系, 为两者融合提供思路。

Abstract

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.
