"REINFORCED EARTH" STEEL RETAINING WALL USED ON HIGH, STEEP SIDE SLOPE IN FRANCE

REINFORCED EARTH STEEL RETAINING WALLS WERE USED TO SUPPORT SECTIONS OF THE FRENCH-ITALIAN HIGHWAY ALONG STEEP SIDESLOPES. REINFORCED EARTH STRUCTURES CONSIST OF A NETWORK OF GALVANIZED STEEL STRIPS INSIDE THE EARTH MASS, AND DESIGNED TO SUPPORT THE EARTH SLOPE AND HIGHWAY PLATFORM. THE FRENCH-ITALIAN HIGHWAY EMPLOYS TEN REINFORCED EARTH STRUCTURES AS HIGH AS 70 FEET. AT VIGNA TWO WALLS WITH TOTAL HEIGHT OF 50 FEET WERE BUILT ON VERY POOR FOUNDATION GROUND, ON A HIGH SLOPE, ON AN ANGLE OF 35 DEGREES. BECAUSE THE SLOPE WAS UNSTABLE, THE EARTH WAS EXCAVATED IN SMALL INCREMENTS AND THE RETAINING WALL INSTALLED BEFORE EXCAVATION WAS CONTINUED. WITH THE USUAL STEEL THICKNESS USED, THE MINIMUM LIFE EXPECTANCY OF THE ECONOMIC REINFORCED EARTH WALLS IS BETWEEN 60 AND 100 YEARS.
