YULVI ZAIKA
TS FT UB

2. THERE ARE TREE COMPONENTS
BACK FILL : GRANULAR SOIL
GEOTEXTILE AS REINFORCEMENT
FACING MUST BE COVERED:
- Bitumen Emulsion

3. INTERNAL STABILITY

8. EXAMPLE:

11. DETERNINATION OF L

12. DETERMINATION OF l1

15. DESIGN GEOGRID The design process of the wall similar to geotextile
Function: reinforcement
There is not lapping in the facing of wall

16. GEOGRID REINFORCEMENT

18. INTERNAL STABILITY

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

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

22. The length of L

23. 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

24. solution
Determine Sv

25. Determine of L
