18、ormation.4. Summary of Guide4.1 This guide describes the type of information that 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 s

19、ubsurface materials and groundwater conditions, in-situ testing, installation of 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, hydrogeo

20、logic, and other investigations of subsurfacesite conditions. This guide may be used 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 log

21、s.NOTE 1- The quality of the result produced by this standard isdependent on the competence 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.

22、Users of this practice are cautioned that compli-ance with Practice D 3740 does not in itself assure reliable results.Reliable results depend on many factors; Practice D 3740 provides ameans of evaluating some of those factors.6.
