Abstract

This paper aims to study and analyze the instability of slopes, their causes and possible remedies. The studied slope is located in Lebanon, and it is regularly subjected to slope instability in the rainfall season. Based on different boreholes results for the same site, two models were modeled using Plaxis and Talren, they were both studied under the effect of water, excavation and seismic load. The results show that the water is a principle cause of slope instability, by decreasing the shear parameters of soil or by the inducing pore pressure due to running water between layers. Many remedies were applied, and their results were analyzed and studied. Soil reinforcements, nails and piles, were applied and as water content increased, the number of reinforcement needed was high. Vegetation and drainage are more efficient when it comes to water problems. Both vegetation and drainage were modeled and the number of needed reinforcement decreased significantly assuring their advantages alongside with the reduction of the remedy price and being environmental friendly.
