1、Designation:D1143/D1143M07(Reapproved 2013)Standard Test Methods forDeep Foundations Under Static Axial Compressive Load1This standard is issued under the fixed designation D1143/D1143M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision
2、,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 The test methods describe
3、d in this standard measure theaxial deflection of a vertical or inclined deep foundation whenloaded in static axial compression.These methods apply to alldeep foundations,referred to herein as piles,that function in amanner similar to driven piles or cast-in-place piles,regardlessof their method of
4、installation,and may be used for testingsingle piles or pile groups.The test results may not representthe long-term performance of a deep foundation.1.2 This standard provides minimum requirements for test-ing deep foundations under static axial compressive load.Plans,specifications,and/or provision
5、s prepared by a qualifiedengineer may provide additional requirements and proceduresas needed to satisfy the objectives of a particular test program.The engineer in responsible charge of the foundation design,referred to herein as the Engineer,shall approve anydeviations,deletions,or additions to th
6、e requirements of thisstandard.1.3 This standard allows the following test procedures:Procedure AQuick Test8.1.2Procedure BMaintained Test(Optional)8.1.3Procedure CLoading in Excess of Maintained Test(Optional)8.1.4Procedure DConstant Time Interval Test(Optional)8.1.5Procedure EConstant Rate of Pene
7、tration Test(Optional)8.1.6Procedure FConstant Movement Increment Test(Optional)8.1.7Procedure GCyclic Loading Test(Optional)8.1.81.4 Apparatus and procedures herein designated“optional”may produce different test results and may be used only whenapproved by the Engineer.The word“shall”indicates aman
8、datory provision,and the word“should”indicates arecommended or advisory provision.Imperative sentencesindicate mandatory provisions.1.5 A qualified geotechnical engineer should interpret thetest results obtained from the procedures of this standard so asto predict the actual performance and adequacy
9、 of piles used inthe constructed foundation.See Appendix X1 for commentsregarding some of the factors influencing the interpretation oftest results.1.6 A qualified engineer shall design and approve all load-ing apparatus,loaded members,support frames,and testprocedures.The text of this standard refe
10、rences notes andfootnotes which provide explanatory material.These notes andfootnotes(excluding those in tables and figures)shall not beconsidered as requirements of the standard.This standard alsoincludes illustrations and appendices intended only for ex-planatory or advisory use.1.7 The values sta
11、ted in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.8 The g
12、ravitational system of inch-pound units is usedwhen dealing with inch-pound units.In this system,the poundlbf represents a unit of force weight,while the unit for massis slugs.The rationalized slug unit is not given,unless dynamicF=ma calculations are involved.1.9 All observed and calculated values
13、shall conform to theguidelines for significant digits and rounding established inPractice D6026.1.10 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 design or otheruses,or both.How on
14、e applies the results obtained using thisstandard is beyond its scope.1.11 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 and health practices and determine the a
