1、Designation:D2573/D2573M18Standard Test Method forField Vane Shear Test in Saturated Fine-Grained Soils1This standard is issued under the fixed designation D2573/D2573M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last
2、 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.Scope*1.1 This test method covers the field vane te
3、st in saturatedclay and silt soils for determination of undrained shearstrength.Knowledge of the nature of the soil in which eachvane test is to be made is necessary for assessment of theapplicability and interpretation of the test.The test is notapplicable for sandy soils or non-plastic silts,which
4、 may allowdrainage during the test.1.2 This test method addresses testing on land and fortesting in drill holes or by self-drilling or continuous pushmethods from the ground surface.This method does notaddress specifically marine testing where special test require-ments or variations in equipment ma
5、y be required.The user isreferred to ASTM STP 1014 for additional information onin-place vane shear testing used in marine exploration.21.3 This method is often used in conjunction with fluidrotarydrilling(D5783),hollow-stemaugers(D6151/D6151M),or cone penetration testing(D5778).Some appara-tuses ha
6、ve the vane retracted in a protective shoe for advance-ment and incremental testing.Sampling,such as with thin walltubes(D1587/D1587M)is often combined with vane testing.Subsurface geotechnical explorations are reported in accor-dance with Practice(D5434).1.4 Undrained shear strength and sensitivity
7、 of cohesivesoils can also be measured in Laboratory Vane Test(D4648/D4648M).1.5 UnitsThe values stated in either SI units or inch-pound units presented in brackets are to be regarded sepa-rately as standard.The values in each system may not be exactequivalents;therefore,each system shall be used in
8、dependentlyof the other.Combining values from the two systems mayresult in non-conformance with the standard.Reporting of testresults in units other than SI shall not be regarded as noncon-formance with this test method.1.5.1 The gravitational system of inch-pound units is usedwhen dealing with inch
9、-pound units.In this system,the pound(lbf)represents a unit of force(weight),while the unit for massis slugs.The rationalized slug unit is not given,unless dynamic(F=ma)calculations are involved.1.6 All observed and calculated values shall conform to theguidelines for significant digits and rounding
10、 established inPractice D6026.1.6.1 The procedures used to specify how data are collected/recorded or calculated in this standard are regarded as theindustry standard.In addition they are representative of thesignificant digits that generally should be retained.The proce-dures used do not consider m
11、aterial variation,purpose forobtaining the data,special purpose studies,or any consider-ations for the users objectives,and it is common practice toincrease or reduce significant digits or reported data to becommensurate with these considerations.It is beyond the scopeof this standard to consider si
12、gnificant digits used in analyticalmethods for engineering design.1.7 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-
13、mine the applicability of regulatory limitations prior to use.1.8 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-mendation
