摘要
东津新区多要素城市地质调查工作区位于湖北省襄阳市东津新区,工作区陆续开展了地质测量、物探、钻探工作。为进一步查明东津新区覆盖低阻层地质背景条件和地质环境特征,探究高密度电法在城市地质调查中的应用,采用温纳装置结合偶极装置方式,通过分析电阻率变化,并结合钻探结果进行验证分析。结果表明高密度电法在100 m浅低阻覆盖层采用温纳排列和偶极排列测量方式与钻探揭示结果吻合度较高,验证了高密度电法在城市地质调查中的有效性和可行性。
The multi-factor urban geological survey work in Dongjin is located in Dongjin New District,Xiangyang City,Hubei Province.The work area has successively carried out geological measurements,geophysical exploration,and drilling activities.In order to further clarify the geological background conditions and geological environmental characteristics of the low-resistance layer covered in Dongjin,and to explore the application of high-density electrical methods in urban geological surveys,a combination of the Wenner device and dipole device was employed.The results indicate that the high-density electrical method,using Wenner and dipole arrangements for measurements in shallow low-resistance cover layers at a depth of 100 meters,shows a high degree of agreement with the findings from drilling.This validates the effectiveness and feasibility of the high-density electrical method in urban geological surveys.
