    摘要:

    中生代白垩纪砖红色、紫红色砂岩、砂页岩致密、较坚硬,一直被水文地质工作者视为弱富水岩层。该文以诸城西北部中生界白垩纪红砂岩碎屑岩类孔隙、裂隙水为研究对象,在现场调查、取样化验、水文地质钻探、抽水试验的基础上,对区内碎屑岩类孔隙、裂隙水水环境进行了初步研究。结果显示,区内碎屑岩类孔隙、裂隙水总体富水性较差,孟疃贾悦断裂北侧受构造及阻水地层影响,形成一个带状富水区;景芝贾悦断裂和吴家楼断裂组交会地带,受多条断裂多次强烈活动,形成断裂破碎带,形成构造富水区。地下水质量较原来趋于变差,NO3呈面状污染。

    Abstract:

    Mesozoic cretaceous brick red, Burgundy sandstone and sand shale are dense and hard, and have been regarded by hydrogeological workers as weakly rich strata. Regarding pore and fissure water in Mesozoic cretaceous red sandstone detrital rock in northwestern Zhucheng city as the research object, on the basis of field investigation, sampling test, hydrogeology drilling and pumping test, the environment of clastic rock pore and fissure water in this area have been studied. It is showed that groundwaterbearing of the fracture water and proe water in the area is relatively poor, and ribbonlike water rich area has been formed in northern Mengtuanjiayue fault which is affected by structures and waterblocking stratum. Fracture zone has been formed in the intersection of Jingzhijiayue and Wujilou fault due to multiple strong activities, and formed water rich zone. The groundwater quality tends to get worse, and NO3 occurred as surface pollution.
