| 摘 要： | 红层高悬台地"顶平、身陡、谷深",具有独特的水文地质特征和地下水富集规律。依据以抗旱打井取得的数据、资料并结合前人已有成果,探讨红层高悬台地在不同地形地貌和地质构造条件下的地下水赋存特点,显示地貌形态与地质构造协调控水。台地中部尤其是沉积盆地边缘,是抗旱找水打井的有利地段。台地边缘地下水可采资源和储存量较少,但在局部地貌汇水有利部位和构造发育地段,可形成局部富水块段,因而应按"贫区中找富块,贫块中找富点"的思路,寻找微型、小型储水构造,找准补给、径流、排汇和含、隔水层关系,准确定位、打井找水。受地形地貌条件所限,红层高悬台地尤其是边缘地带地下水位埋藏较深,宜尽量打深井揭至侵蚀基准面以下,才更有可能多出水。

| Abstract: | Hanging platform of red - beds are plat top, steep body and deep valleys, with a unique hydrogeolog- ical characteristics and groundwater enrichment patterns. Basing on the data and information of drilling wells for drought, and previous existing achievements, it is discussed that the characteristics of the red - beds hanging plat- form to the different topography and geological structure under the conditions of groundwater occurrence. Water controlling is coordinated to topography and geological structure. A favorable location of drilling for water is the tableland central, especially the edge of the sedimentary basin. Groundwater recoverable resources and storage ca- pacity are less in the edge of tableland. But the local water - rich block is formed in the local geomorphological catchment favorable location and tectonic development of the lot.Thus, looking for the micro, small storage structure, identifying the relationship of supply, runoff, remit and containing the impermeable layer, accurate positioning, drilling wells to find water should be done according to the idea of ＂poor area looking for rich and poor block to find rich point＂ . Being limited by the topography conditions, the groundwater level is very deep in the red - beds hanging platform, especially the fringe. Try to drill deep well to below the base level of erosion so that more than water are more likely to be drilled. |
