Determination le Step 4 : Calculate the length of each layer of geogrid at a depth z as

EXTERNAL STABILITY CECK FOR OVERTURNING CHECK FOR SLIDDING CHECK FOR BEARING CAPACITY

The length of L

EXAMPLE Consider a geogrid retaining wall given H=6m, 1=16,5 kN/m3, =350, Tall=45 kN/m. FS(B)=1,5, FS (P)=1,5, Cr=0,8 and Ci=0,75. For design of retaining wall, determine Sv and L

solution Determine Sv
