Step 7 <br /> • Establish the maximum allowable strain (TAS) 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(ZR). Typically <br /> the Factor of Safety(FS)is equal to 2. <br /> Z <br /> T ALJ- = R <br /> FS <br /> Step 8 <br /> • Determine the Tensile Strength (TR)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 (tom) in the Liner System. <br /> 92 at Z'ALL (From Table 2) <br /> AdIk TR =2PNYl <br /> Step 9 <br /> • Determine the Long Term Allowable Design Strength(LTADS)of the <br /> selected Geogrid. <br /> TSTA TTS <br /> LTADS = FS CR x FSD x]'-SID x FSS <br /> where <br /> TS7.ATtALL — Short Term Tensile Strength(per GRI GGI) measured at <br /> the maximum allowable strain (TALI.) <br /> (g) <br />
