摘    要:从常规组分、微量元素和氢氧同位素三方面,分析毛坝向斜岩溶水的动力环境特点和起源。结果表明:大气水是毛坝向斜岩溶水的唯一来源;至今尚未形成统一的岩溶水系统,核部与翼部岩溶水有其相对独立性,但又存在相互越流补给;受断层影响存在两相地下集水凹陷带;半节河的水量主要来源于大冶灰岩岩溶水的补给。

关 键 词:岩溶水 水动力环境 水化学 同位素 圆梁山隧道 大气降水

INDICTION OF HYDRODYNAMIC CONDITIONS THROUGH HYDROCHEMISTRY AND ISOTOPES AT MAOBA SYNCLINE

Abstract:Based on the observed data about major components, trace elements and hydrogen and oxygen isotopic compositions, This paper discusses the hydrodynamic conditions and the flow system of the Karst water at Maoba syncline. There is not an integrated flow system yet at Maoba syncline. And the precipitation is the unique source of groundwater in Maoba. From the analysis, we also found that there is an underground water-catch depression in the area where the tunnel passes by. Obviously, it will be harmful to the construction and running of the long deep tunnel.
Keywords:maoba syncline  Karst water  hydrodynamic conditions  hydrochemistry-Isotope
