水体是工程空间结构的重要因素之一, 也是空间活动的载体。西藏高原素有“世界第三极”之称, 地理位置特殊, 部署有大量工程基建, 因此高原环境下如何建设好各项中大工程, 对水体的重视需进一步加强。本文通过对西藏格达乡地区地质条件调查, 对区内水体机理性能分析梳理, 通过实地发现, 调查区水体走向受构造与地形控制; 同时, 工程给水保障主要是针对水质水量信息进行定性和定量评价, 调查区工程给水保障主要分为地表水的给水保障和地下水的给水保障两部分, 本文阐述地下水保障相关内容, 通过实地调查及野外水质采集, 调查区域内基本情况为: 地下水水质总体优于地表水, 尤其是多吉林泉水, 水质较好, 水量较大; 对其他区域水质调查及地质工程建设有指导意义。

Water body is one of the important factors of engineering spatial structure, and also the carrier of spatial activities. The Tibetan Plateau is known as the “third pole in the world”. It has a special geographical location and a large number of projects for engineering infrastructure. Therefore, how to build various major and large-scale projects under the plateau environment needs to be further strengthened to the importance of water bodies. In this paper, through the geological conditions in Geda Township, Tibet, Analysis and performance of water mechanism in the area, through the field discovery, The water direction in the survey area is controlled by the structure and terrain; at the same time, the project water supply guarantee is mainly for the qualitative and quantitative evaluation of water quality and quantity information, the water supply guarantee of the investigation area is mainly divided into surface water supply water guarantee and groundwater water supply guarantee. This paper describes the relevant content of groundwater protection, through the field investigation and field water quality collection, the basic situation in the investigation area is that: the groundwater quality is generally superior to that of the surface water, especially more than Jilin spring water, better water quality and larger amount of water; It is of guiding significance to water quality investigation and geological engineering construction in other areas.
