A live uniform surcharge of 24 kN/m 2 is considered to be acting on the reinforced wall.

WebbDetails of the "tie back wedge" method is described BS8006. In the document HA64/98, the limit equilibrium approach is also adopted for designing reinforcement of steep slopes. It also incorporates partial factors and the design is based on a two-part wedge mechanism which is preferred because it provides a WebbThe confining effect is introduced into the tie-back wedge method of geogrid-reinforced retaining walls in a practical design. A new formula for calculating the maximum tensile force mobilized on the sliding plane on Rankine’s active earth pressure theory was derived. perkspot main line health
