ABSTRACT: In this study, six composite reinforcements such as
cement composite made of Abandoned Cell Husks (ASH), Stones, Wood chips,
Concrete and Bricks have been used along with control specimen. It is known
that the material used in earth reinforcement applications must be safe against
tension failure and adhesion failure for its effective utilization in the field
and reliable design of earth structures. Single type of material can provide
limited reinforcement capability in reinforced earth structures due to its low
frictional resistance and poor cohesion. For an optimal response, therefore,
composite reinforcement, that fulfils both the requirements such as possess
adequate tensile strength and adequate frictional resistance, is getting
considerable attention. Slope stability analyses containing six types of
reinforcement have been performed. Stability of the slope has been quantified
using minimum factor of safety corresponding to critical slip surface. It was
observed that the composite reinforcement whose surface treated by brick
aggregate enhanced the factor of safety significantly. The paper also depicted
the design aids of reinforced slope in terms of embedding lengths and spacing
of reinforcements.
