ABSTRACT

Slope stability is one of the most important problems in geotechnical engineering because failure could cause catastrophic environmental and human disaster, in addition to large economical losses due to such failure. The simplest solution to handle with slope failures is to avoid the failed zones and choose safer locations to move the projects which are decided to be constructed nearby the failed slopes. The paper delineates the effects of geofoam on soft clayey slopes which contain weak layers. This emphasis is given to the slope geometry, loading, and geofoam material that are numerically simulated using the finite element technique. In addition, the proposed stabilizing system is employed, presented, and analyzed. The analysis of the embankment is performed by the limit equilibrium analysis program (Slide V6.003). The increase in the geofoam thickness from 0.0m to 1.0m resulted in a noticeable increase in the safety factor for loaded and unloaded slopes. On another hand, increase in geofoam thickness from 1.0m up to 4.0m in case of unloaded slope, the safety factor is still constant for about 2.10. A consistent increase in the safety factors is noticed as a result of increasing the geofoam thickness from 0.0m up to 4.0m. Moreover, there is a slight decrease in the safety factor for loaded slopes during different values of geofoam position from the road level. The main factors which affect the slopes stabilized with geofoam such as, geofoam width, thickness, and position of the geofoam from the road level are also presented and discussed.
