泥灰岩岩溶裂隙类型及其富水性

THE TYPE OF MARLITIC KARST FISSURE AND ITS WATER-RICH PROPERTY

目前,在地下水开发工作中,国内不少地区有泥灰岩作为隔水层或弱透水层。作者从近几年来沂蒙山区泥灰岩层地下水开发实践中,总结出泥灰岩的富水条件。根据大量的钻孔资料,将泥灰岩岩溶裂隙型划分为水锤作用、结构成因、组合结构、构造作用和复合作用五种成因类型,并分析了各类型的富水性。

At present, in the work of groundwater exploitation marlite has been regarded asaquiclude or bad permeable stratum in many internal areas in China. In recent years, the au-thor have summed up the water-rich conditions of marlite from the practice of marlitic ground-water exploitation in Yi-Meng mountain area. According to a lot of drillhole information, the type of marlific karst fissure might be divided into five kinds of contributing factor: effect of water hammer, contributing factor of structure, composed structure, tectonic effect and compound effect. And the water-rich property of each type is expounded.
