沂南县贫水山区找水定井技术研究

Research on Borehole Location Techniques in Water Shortage Mountain Areas in Yinan County

摘要:

综合分析沂南县气候、自然、地理，尤其是地质与水文地质条件，及2011年国土资源抗旱打井工作成果，结合沂南地下水含水岩组分布、赋存、地下水运移特征、构造对岩溶发育与地下水运动的控制等。得出沂南县岩溶地下水补给径流区的构造破碎带及其附近地下水相对富集。地下水富集特征可分为：构造带控水型、火成岩体阻挡富水型、断裂影响带强富水型及远离构造破碎带弱富水型等几种类型。根据岩溶地下水补给径流区地下水富集规律的分析研究，为今后贫水山区找水定井提供参考。

Abstract:

Through analyzing physical geography, geology and hydrogeology condition, combining with characteristics of distribution, occurrence and movement of groundwaterbearing layers, and influence of geological structures on karst development and groundwater movement, it is concluded that groundwater is relative enrichment at tectonic fracture zone of runoff replenishment areas. Characteristics of groundwater enrichment can be divided into structural belt controlling type, igneous bodies barrier richwater type, faults influencing abundant water type and away fracture zone weakenrichment water type. Through study and analysis on groundwater enrichment rules of groundwater recharge to groundwater runoff, it will provide some references for borehole location in water shortage mountain areas.
