摘要
为解决莆田南日岛居民用水问题,在南日岛地区应用高密度电阻率法进行找水,通过高密度反演软件RES2DINV对测试数据进行二维反演得到二维视电阻率反演断面图。根据反演结果推断地下深处发育有断层破碎带,2个验证钻孔揭露情况与高密度反演结果基本吻合,风化基岩与深部基岩接触面含断层破碎带,抽水试验计算得出的单井出水量分别为420m3/d和62.2m3/d。
High density resistivity method was applied to search water in Nanri Island for solving residential water use. problems 2 D inversion apparent resistivity section image was obtained by inversing test data with high-density inversion software. The inversion results show that there is fault fracture zones developing in deep strata. High-density inversion results match the data detected by two verifying boreholes. The contact surface between weathered bedrock and deep bedrock includes fault fracture zones. Yields of single dewatering well calculated by pumping test are 420 m3/d and 62.2 m3/d.
