A study on simplified slope stability analysis for reinforced embankments containing various types of reinforcements have been conducted using Microsoft excel spreadsheet technique. The selected reinforcing materials that have been identified for reinforced embankments are composite materials with smooth surface and rough surface made of Abandoned Cell Husks (ASH), Stones, Wood chips, Concrete and Bricks. The most critical slip surface which showed Minimum Factor of Safety (Fsmin) has been identified based on random search technique. Results for different reinforced embankments having slope angles 30o, 45o and 60o with varying reinforcing layers and spacing corresponding to the most critical slip surface are given. Relationships of slope inclinations with coefficients of frictional resistance for reinforced embankments containing six types of porous composite materials have been depicted in order to ease in the design process.
