摘要
针对溪洛渡巨型水利枢纽工程在玄武岩坝址区的勘探中遇到的较为复杂的水文地质异常现象 ,如冷水与热水、裂隙水“承压”现象、偶遇大水量突水点等异常现象 ,通过运用地下水流动系统理论 ,构建了坝区地下水流动系统模式 ;揭示了深部灰岩水越层排泄和玄武岩潜水混合排泄带的特征 ,以及浅部以层间层内裂隙发育为主的非均质玄武岩含水介质的特点 ;阐明了坝区地下水异常现象的成因与条件。
In prospecting for the basaltic dam area of Xiluodu Hydroelectric Station, authors encountered many complicated hydrogeological phenomena,such as hot water, confined fractured water and emergency breakout water.By establishing patterns of groundwater flow system in the area based on theory of groundwater flow system,They have revealed the characteristics of discharge zone mixed with deep confined karst water and shallow phreatic basal water and heterogeneity of basal aquifer developed layered fractures and thus explained the formation of the groundwater unconventionality.
