Parametric Studies on the Behaviour of Reinforced Soil Retaining

Figure 2.13: Fellenius Method of Analysing Reinforced Soil Structures
There are two reinforcement effects of the tensile force generated in the
reinforcements in the sliding surface (see Fig. 2.13).
(1) Anchoring effect,
(2) Confining effect,
Regarding the confining effect (2), involves the equation, Eq. (2.1), and regarding the
anchoring effect (1), two possible conditions arise, it may be considered as a resisting
force (numerator) and as a sliding force (denominator). Sometimes, both effects are
considered simultaneously together depending on the problem. Thus following five
combinations can be derived by coupling these two effects with the Eq. (2. 1).
