摘要
来安县半塔林场地处皖东玄武岩台地之上,属江淮分水岭东段地下水贫水区。通过专项地质调查、综合电法工作,发现了断层,结合区域构造变形特征、分布特点以及应力场变化特征等进行初步分析,确定了断层的力学特征和含(透)水性,并施工了SJ01、SJ02水源井验证;经SJ02抽水试验表明:该水源井日出水量可达400 t,水质良好;解决了半塔林场约750人的生活饮用水困难,取得了明显的经济效益和社会效益。
Located on the basaltic platform in eastern Anhui Province,the Banta forest farm in Lai’an County belongs to a groundwater-shortage area in the east section of the Jianghuai watershed.Dedicated geological survey and comprehensive electrical method led to the discovery of a fault,whose mechanical characteristics and water-containing capacity(and transmissivity)were identified through initial analysis of the deformation,distribution and stress field variation characteristics of regional structures.Water supply wells SJ01 and SJ02 were constructed for verification.The well SJ02 pumping test showed daily yield of 400 t water of good quality,which resolved the issue of drinking water for about 750 people of the farm,bringing remarkable economic and social benefits.
