Step 7 <br /> • Establish the maximum allowable strain (TALL) in the liner system. <br /> Note: On liner support applications, it is the state of practice to apply <br /> the Factor of Safety(FS)to.the multiaxial rupture straiir(TR). Typically <br /> the Factor of Safety(FS)is equal to 2. <br /> T <br /> T.4LJ- = R <br /> R <br /> Step 8 <br /> • Determine the Tensile Strength (7R)required in a single layer ofgeogrid <br /> to support the lining system above the yielding foundation. <br /> Note: The Tensile Strength of the geogrid must be compatible with the <br /> maximum allowable strain (TALL) in the Liner System. <br /> 92 at I-ALL (From Table 2) <br /> TR =2P rlSZ <br /> Step 9 <br /> • Determine the Long Term Allowable Design Strength(LTA.DS)of the <br /> selected Geogrid. <br /> LTADS = 7'S7-ATTAU <br /> FSCR X FSn x"-SAID x FSJW7S <br /> where <br /> TS7-ATTALL = Short Term Tensile Strength(per GRI GGI)measured at <br /> the maximum allowable strain (t ) <br /> AL/.. <br />
