【摘要】 昌都市地处高山峡谷红层区,含水层普遍较薄,地下水资源贫乏,水源地需要选在在水文地质条件相对较好的地段,并采用符合当地实际的取水方案。昌都二水厂水源地勘察过程中,首先查清了当地的水文地质条件,其含水层厚度小于12m,但渗透系数多大于100m/d,地下水主要依靠河水下渗补给,具有"就地补给,就近排泄"的特点。根据这些特征,勘查开发中设计了辐射井工程,取得了非常好的效果。通过昌都二水厂的成功经验,认为辐射井适合在类似的高山峡谷区取水,值得推广。更多还原

【Abstract】 Changdu City lies in the alpine canyon red layer area characterized by thin aquifer and poor in groundwater resources.Hydrogeological condition of the second water plant site of Changdu City is characterized by aquifer thickness of less than 12 m,river recharge with a filtration coefficient of more than 100 m/d.Accordingly,radial wells are designed for hydrogeological exploration of the second water plant of Changdu City,obtaining good results.更多还原
