Step 7 <br /> • Establish the maximum allowable strain (TALI) 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 strain (TR). Typically <br /> the Factor of Safety (FS) is equal to 2. <br /> Z <br /> R <br /> Z <br /> ALL — F.S' <br /> Step 8 <br /> Determine the Tensile Strength (TR)required in a single layer of geogrid <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 /> D at T ALL (Fr-om Table 2) <br /> TR =2P r,Q <br /> Step 9 <br /> • Determine the Long Term Allowable Design Strength(LTADS)of the <br /> selected Geogrid. <br /> TSTA7'T ALL <br /> LTADS = FSCR x "SD x 1-SID x rSJ, S <br /> where <br /> TSTAT"ALL = Short Term Tensile Strength (per GRI GGI) measured at <br /> the maximum allowable strain (TALL) <br /> ) <br /> (8) <br />
