Designation:D575318Standard Guide forPlanning and Conducting Geotechnical BoreholeGeophysical Logging1This standard is issued under the fixed designation D5753;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 Purpose and Application:1.1.1 This guide covers the documentation and generalprocedures necessary to plan and conduct a geophysicalborehole logging program as commonly applied to geologic,engineering,groundwater,and environmental(hereafter re-ferred to as geotechnical)site characterizations.1.1.2 This guide applies to commonly used logging methods(see Tables 1 and 2)for geotechnical site characterizations.1.1.3 This guide provides an overview of the following:(1)the uses of single borehole geophysical methods,(2)general logging procedures,(3)documentation,(4)calibration,and(5)factors that can affect the quality of borehole geophysi-cal logs and their subsequent interpretation.Log interpretationis very important,but specific methods are too diverse to bedescribed in this guide.1.1.4 Logging procedures must be adapted to meet theneeds of a wide range of applications and stated in generalterms so that flexibility or innovation are not suppressed.1.1.5 To obtain detailed information on operating methods,publications(for example,1,2,3,4,5,6,7,8,and 9)2shouldbe consulted.A limited amount of tutorial information isprovided,but other publications listed herein,including aglossar y of terms and general texts on the subject,should beconsulted for more complete background information.1.2 Limitations:1.2.1 This guide is not meant to describe the specific orstandard procedures for running each type of geophysical log,and is limited to measurements in a single borehole.1.2.2 Surface or shallow-depth nuclear gages for measuringwater content or soil density(that is,those typically thought ofas construction quality assurance devices),measurementswhile drilling(MWD),cone penetrometer tests,and loggingfor petroleum or minerals are excluded.1.2.3 This guide offers an organized collection of informa-tion or a series of options and does not recommend a specificcourse of action.This document cannot replace education orexperience and should be used in conjunction with professionaljudgment.Not all aspects of this guide may be applicable in allcircumstances.This ASTM standard is not intended to repre-sent or replace the standard of care by which the adequacy ofa given professional service must be judged,nor should thisdocument be applied without consideration of a projects manyunique aspects.The word“Standard”in the title of thisdocument means only that the document has been approvedthrough the ASTM consensus process.1.3 Precautions:1.3.1 If the method is used at sites with hazardous materials,operations,or equipment,it is the responsibility of the user ofthis guide to establish appropriate safety and health practices,and to determine the applicability of regulations prior to use.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.1This guide is under the jurisdiction ofASTM Committee D18 on Soil and Rockand is the direct responsibility of Subcommittee D18.01 on Surface and SubsurfaceCharacterization.Current edition approved Feb.1,2018.Published March 2018.Originallyapproved in 1995.Last previous edition approved in 2010 as D575305(2010).DOI:10.1520/D5753-18.2The boldface numbers in parentheses refer to a list of references at the end ofthis standard.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 TABLE 1 Common Geophysical LogsType of Log(References)Varieties and RelatedTechniquesProperties MeasuredRequired HoleConditionsOther LimitationsTypical MeasuringUnits and Calibrationor StandardizationBrief ProbeDescriptionSpontaneous potential(7,8,12)differentialelectric potentialcaused by salinity
