1、Designation:D710011(Reapproved 2020)Standard Test Method forHydraulic Conductivity Compatibility Testing of Soils withAqueous Solutions1This standard is issued under the fixed designation D7100;the number immediately following the designation indicates the year oforiginal adoption or,in the case of
2、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 This test method covers hydraulic conductivity compat-ibility testing of saturated soils in the labora
3、tory with aqueoussolutions that may alter hydraulic conductivity(for example,waste related liquids)using a flexible-wall permeameter.Ahydraulic conductivity test is conducted until both hydraulicand chemical equilibrium are achieved such that potentialinteractions between the soil specimen being per
4、meated andthe aqueous solution are taken into consideration with respectto the measured hydraulic conductivity.1.2 This test method is applicable to soils with hydraulicconductivities less than approximately 1 108m/s.1.3 In addition to hydraulic conductivity,intrinsic perme-ability can be determined
5、 for a soil if the density and viscosityof the aqueous solution are known or can be determined.1.4 This test method can be used for all specimen types,including undisturbed,reconstituted,remolded,compacted,etc.specimens.1.5 Aspecimen may be saturated and permeated using threemethods.Method 1 is for
6、saturation with water and permeationwith aqueous solution.Method 2 is for saturation and perme-ation with aqueous solution.Method 3 is for saturation withwater,initial permeation with water,and subsequent perme-ation with aqueous solution.1.6 The amount of flow through a specimen in response toa hyd
7、raulic gradient generated across the specimen is measuredwith respect to time.The amount and properties of influent andeffluent liquids are monitored during the test.1.7 The hydraulic conductivity with an aqueous solution isdetermined using procedures similar to determination of hy-draulic conductiv
8、ity of saturated soils with water as describedin Test Methods D5084.Several test procedures can be used,including the falling headwater-rising tailwater,the constant-head,the falling headwater-constant tailwater,or the constantrate-of-flow test procedures.1.8 UnitsThe values stated in SI units are t

10、m of inch-pound units is usedwhen dealing with inch-pound units.In this system,the pound(lbf)represents a unit of force(weight),while the unit for massis slugs.1.8.3 The slug unit of mass is almost never used incommercial practice;i.e.,density,balances,etc.Therefore,thestandard unit for mass in this
11、 standard is either kilogram(kg)or gram(g),or both.Also,the equivalent inch-pound unit(slug)is not given/presented in parentheses.However,the useof balances or scales recording pounds of mass(lbm)orrecording density in lbm/ft3shall not be regarded as noncon-formance with this standard.1.9 This stand
