摘要
青海省海北藏族自治州刚察县热水镇地处祁连山腹地,工作区属高原沼泽区,隐伏断裂较多。为了解工作区内地层结构及活断层分布,采用高密度电阻率法获取地下电性特征,预处理剔除畸变点之后,利用有限差分法正演及最小二乘法反演,结果表明高密度电阻率法在本次工作中能有效探测出活断层位置。
Reshui Town in Gangcha County,Qinghai Province,is in the interior of Qilian Mountains.The working area is a plateau swamp area with many hidden faults.To understand the stratigraphic structure and active fault distribution in the working area,high-density resistivity method was used to obtain the underground electrical characteristics.After removing the distortion points through preprocessing,finite difference forward modeling and least square inversion were used.The results showed that high-density resistivity method can effectively detect the location of active faults in this work.
