1 Local Experience, Worldwide Expertise Reinforced Earth İnşaat Proje ve Ticaret A.Ş. Alemdar, Merkez Mah. Şehit Murat Demir Cad. No:69/D ÜMRANİYE İSTANBUL TURKEY Tel. : (+90) Fax : (+90)

2 BACKGROUND Reinforced Earth wall system was invented by French Engineer Henry Vidal in Reinforced Earth wall system is recognized as a major innovation in the field of civil engineering. More than 35 million m 2 wall have been completed all over the world. 2

3 PRINCIPLE Reinforced Earth is based on very simple concept. The frictional forces developed at the contact points between compacted granular fill and reinforcing strips result in a permanent bond providing a composite material. Components; Facing Panels Galvanised Steel Strips Connection Parts (Lugs, Bolts and Nuts) Granular Backfill 3

4 FACING PANELS Panel type and dimensions are based on wall height and geometry. Erection of standard A4 type panel Cut panel examples 4

5 GALVANISED HIGH ADHERENCE STEEL STRIPS The reinforcing strips are high adherence medium tensile steel with a rupture strength of not less than 510 N/mm 2 and hot dipped galvanized to provide a coating of not less than 70 μm. 5

6 CONNECTION PARTS Steel strips are bolted to lugs, which are already inserted in pre-cast concrete facing panel 6

7 GRANULAR BACKFILL Reinforced Earth Backfill Material Gradation Sieve Size (mm) 125 (5 ) 75 (3 ) 12.5 (1/2 ) 2 (No.10) 0.59 (No.30) (No.200) Percent Passing Max. 15 Also, Cu >5 & PI <6 7

8 CONSTRUCTION PROCESS Panel pre-casting and storage Construction of levelling pad and Panel Placement Filling and compacting each strip layer Connecting strips to the panels, filling and compacting Construction of coping units 8

9 PANEL PRECASTING AND STORAGE Concrete Facing Panels Compressive strength; Cube strength to be not less than 34 N/mm 2 Cylinder strength to be not less than 27 N/mm 2 Typical Pre-casting Yard 9

10 PANEL PLACEMENT FOR INITIAL COURSE 10

11 ERECTION OF BOTTOM PANELS 11

12 COMPACTION OF BACKFILL Backfill is carried with traditional machinery and compacted in 37.5 cm thick layers. 12

13 CONNECTING STEEL STRIPS AND PANELS 13

14 CONSTRUCTION OF COPING UNITS 14

15 DESIGN CONCEPT Utilization of Valdez Software (TAI program) Analysis of; External Stability Internal Stability 15

16 DESIGN CONCEPT External Stability Overturning Check Base Sliding Check 16

17 DESIGN CONCEPT Internal Stability Strip Rupture Check Connection Check Adherence Check 17

18 ADVANTAGES Earthquake resistance Flexibility, making it possible to build directly on compressible foundation soils Ease of installation Considerable Savings Providing Aesthetic view Providing possibility to work in limited spaces 18
