17、dard:3.2.1 field loga record prepared during subsurface explo-rations of soil and rock to document procedures used, test data,descriptions of materials and depths where encountered,ground water conditions, and other information.4. Summary of Guide4.1 This guide describes the type of information that

18、 shouldbe recorded during the execution of field subsurface explora-tions in soil and rock. The information described relates to theproject, personnel, methods of investigation and equipmentused, visual description of subsurface materials and groundwater conditions, in-situ testing, installation of

19、monitoringequipment, and other data that may be appropriate.5. Significance and Use5.1 The preparation of field logs provides documentation offield exploration procedures and findings for geotechnical,geologic, hydrogeologic, and other investigations of subsurfacesite conditions. This guide may be u

20、sed for a broad range ofinvestigations.5.2 The recorded information in a field log will depend onthe specific purpose of the site investigation. All of theinformation given in this guide need not appear in all field logs.NOTE 1The quality of the result produced by this standard isdependent on the co

21、mpetence of the personnel performing it, and thesuitability of the equipment and facilities used. Agencies that meet thecriteria of Practice D 3740 are generally considered capable of competentand objective sampling. Users of this practice are cautioned that compli-ance with Practice D 3740 does not

22、 in itself assure reliable results.Reliable results depend on many factors; Practice D 3740 provides ameans of evaluating some of those factors.6. Summary of Work6.1 Soil and rock field logs should include the followingwritten information:6.1.1 Project information should include:6.1.1.1 Name and loc

23、ation of the project or project number,or both,6.1.1.2 Name of personnel onsite during the exploration,such as drilling crew, supervisor, geologist, engineer, andtechnicians,6.1.1.3 Names and addresses of organizations involved,6.1.1.4 Name of person(s) preparing log,6.1.1.5 Reference datum for proj

Deflection of the drill bit due to inclined bedding andhard boulders are some of t

30、he many reasons a drill hole might deviatefrom the intended direction. Drill holes that deviate from the intendeddirection can give erroneous data if not corrected. This can lead tosignificant interpretation errors of subsurface conditions and geologicstructure. Depending on intended use of the data
