Abstract
This paper covers analysis of the application of the geo-synthetics materials for the reinforcement technology of slope stability damaged by heavy rain fall is targeted. For this purpose, three parallel layers model which generate tensional force moving apart from the original slope is utilized to simulate qualitatively. This model helped to but approximately a sliding force generated by infiltration of water from surface of ground and rising of ground water from sliding plane. Evaluation of proper use case and efficiency level of geo-synthetics materials are performed on the results of analysis using the proposed model. Also the paper refers that the role of geo-synthetics is expanded to connect with various kind of small change of slope protection.
