Designation:D738310Standard Test Methods forAxial Compressive Force Pulse(Rapid)Testing of DeepFoundations1This standard is issued under the fixed designation D7383;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.Scope1.1 These test methods cover procedures for testing anindividual vertical or inclined deep foundation to determine thedisplacement response to an axial compressive force pulseapplied at its top.These test methods apply to all deepfoundation units,referred to herein as“piles,”that function ina manner similar to driven or cast-in-place piles,regardless oftheir method of installation.1.2 Two alternative procedures are provided:1.2.1 ProcedureAuses a combustion gas pressure apparatusto produce the required axial compressive force pulse.1.2.2 Procedure B uses a cushioned drop mass apparatus toproduce the required axial compressive force pulse.1.3 This standard provides minimum requirements for test-ing deep foundations under an axial compressive force pulse.Plans,specifications,provisions(or combinations thereof)prepared by a qualified engineer,may provide additionalrequirements and procedures as needed to satisfy the objectivesof a particular deep foundation test program.The engineer inresponsible charge of the foundation design,referred to hereinas the“Engineer,”shall approve any deviations,deletions,oradditions to the requirements of this standard.1.4 The proper conduct and evaluation of force pulse testingrequires special knowledge and experience.A qualified engi-neer should directly supervise the acquisition of field data andthe interpretation of the test results so as to predict the actualperformance and adequacy of deep foundations used in theconstructed foundation.A qualified engineer shall approve theapparatus used for applying the force pulse,rigging andhoisting equipment,support frames,templates,and test proce-dures.1.5 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of the standard.The word“shall”indicates amandatory provision,and the word“should”indicates arecommended or advisory provision.Imperative sentencesindicate mandatory provisions.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 All observed and calculated values shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.8 The method used to specify how data are collected,calculated or recorded in this standard is not directly related tothe accuracy to which the data can be applied in the design orother uses,or both.How one uses the results obtained usingthis standard is beyond its scope.1.9 ASTM International takes no position respecting thevalidity of any patent rights asserted in connection with anyitem mentioned in this standard.Users of this standard areexpressly advised that determination of the validity of any suchpatent rights,and the risk of infringement of such rights,areentirely their own responsibility.1.10 This standard may involve hazardous materials,operations,and equipment.This standard does not purport toaddress all of the safety concerns,if any,associated with itsuse.It is the responsibility of the user of this standard toestablish appropriate safety and health practices and deter-mine the applicability of regulatory limitations prior to use.Section 7 provides a partial list of specific hazards andprecautions.2.Referenced Documents2.1 ASTM Standards:2D653 Terminology Relating to Soil,Rock,and ContainedFluids1These test methods are under the jurisdiction ofASTM Committee D18 on Soiland Rock and is the direct responsibility of Subcommittee D18.11 on DeepFoundations.Current edition approved July 1,2010.Published August 2010.Originallyapproved in 2008 as D738308.DOI:10.1520/D7383-10.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 D1143 Test Method for Piles Under Static Axial Compres-sive Load(Withdrawn 2005)3D3689 Test Methods for Deep Foundations Under StaticAxial Tensile LoadD3740 Practice for Minimum Requirements for AgenciesEngaged in Testing and/or Inspection of Soil and Rock asUsed in Engineering Design and ConstructionD5882 Test Method for Low Strain Impact Integrity Testingof Deep FoundationsD6026 Practice for Using Significant Digits in GeotechnicalDataD6760 Test Method for Integrity Testing of Concrete DeepFounda
