摘要
蓄水构造理论已在基岩山区找水中显示出它是科学的、先进的、实用的。如果把这一理论应用到水文地质图件的编制上,势必将更好地反映出地下水的赋存状态与分布规律。作为一种尝试,笔者根据大量的实际资料,编制出《朝阳地区蓄水构造类型图》。该图表现三种内容:1)蓄水构造的类型,2)富水结构的种类及其分布规律,3)地下水露头及其他。该图具有两个特点:1)在基本蓄水构造类型的基础上,根据岩性、构造相结合的原则,划分出亚类,并以这些亚类作为基本编图单位。这样,既全面地反映了控水因素,又方便了编图单位的画定;2)将基岩的蓄水构造进一步划分为具有成生联系、水力联系的三种水文地质结构,称之为富水结构、导水结构、阻水结构。图中仅反映富水结构的种类及其分布规律。其结果,更为确切地反映了地下水的分布规律,突出了富水部位,从而增进了这种水文地质图的实用性。
The theory of water-bearing structure has been proved to be a scientific, practical and advanced theory in finding ground water in a mountainous region.If the theory in was applied to compiting a hydrogeological map,the attitude and distribution of ground water would be shown better on it.As a kind of attepmpt,the author has worked out a map to show the water-bearing structural types of Chaoyang area on the basis of conside rable practical data,The map show 1)the types of water-bearing structure,2)the kinds and distribution of water-rich framework,3)the out crops of ground water and so on.It has the following two characters:1)Based on the principle of combining lithological characters with structure,The fundamental water- bearing structural types have been divided into some subtypes used as the basic units of compiting the map.Thus the subtypes not only can comqletely expresses water-controlling factors but also make the division of the units more convenient.2)The water-bearing structures have been subdivided into the three types of hydrogeological fra meworks having genetic and hydraulic relations,i.e.waterrich,water-transmitting and water-resisting frameworks.The map only shows the types and distri- bution of the water-rich framework.As a result,the law of groundwater distribution is expressed assuredly and the water-rich locations are protruded on the map.Thus the practicality of hydrogeological map has been promoted.
