Research On The Application Of Resistivity Method To The Exploration Of The Formation Structure In The Coastal Plain

Special regional geological survey is an important direction of geological survey work now.As a developed economic region in China,coastal area development and construction relies on the support of basic geological information.The basic geological survey data of which plays an important role in the development of regional economy.This thesis studies on the resistivity acquisition methods and analysis on the response characteristics of geoelectric field.Research works mainly include:(1)Make studies on the response characteristics of geoelectric field and adopts the traditional resistivity sounding method and high-density method.Through contrasts the advantages and disadvantages between the two methods and compare their applicability in coastal plains.The article which focused on research on response characteristics for geoelectric field with resistivity sounding method in coastal plains.Conclusion combined with the data from borehole information and hydrogeological data.Mainly by conducting a series of experiments such as max spacing of electrodes,best electrodes spacing,power supply testing,consistency check on instruments.Arriving at the main parameters that should be taken for extensive and high-precision geological survey in coastal plain.(2)The research on main types of electrical deep curve was involved,by setting up survey line besides boreholes.Validate the real effects of resistivity method.This artical introduced the line layout along different directions and study the different characteristics in shallow-buried earth.For purpose of the follow-up work for reference.(3)Based on text date achievement available in experiment,to investigate the shallow earth in Jiangshan Town.Make detection for aquifer structure and buried depth of bedrock.Which delineated the salt water and brackish water structure,aquifer structure and beadrock heaved situation in parts of Southern within the range of survey line around Jiangshan TownThe paper is conducted herein the applicability of resistivity exploration work in coastal plains.Generally as for the hydrogeology research work in salt and fresh water boundary delimitation,acquifer conditions study.Resistivity method also worked well and has good response characteristics.
