Groundwater occurrence characteristics and drilling well models in karst peak forest areas,Guangxi,China
摘要
Abstract
Based on drilling well data for fight against drought recent years in karst peak forest areas of Guangxi,this work analyzed the relations between hydrogeologic conditions and drilling wells.The results show that structure,lithology and karst development horizons are the main control factors for drilling wells. The water-bearing structures such as fault fracture zones,synclines or anticlines and contact zones between aquifers and relative water-resisting layers are favorable drilling sites to find groundwater.The carboniferous strata (C1 ,C2 )and the upper Devonian system strata (D3 )are the main drilling formations,occupying 55.24% of the total number of wells with the mean water yield of 261 m3 ·d-1 for each single well.Ground-water extraction depth is 37.67 m on average.Through the analysis of the occurrence characteristics and law of karst waters,six types of drilling well models are suggested.Meanwhile several common landform fea-tures are considered as marks for water search.关键词
