The construction of structures on soft ground includes many problems. Soft ground- treatment method is necessary to increase in the stability of the soil-structures. Now Geosynthetic reinforced soil method of many soft ground treatment methods is being used widely by the economical and simple method. And the usage is increasing. It has been proved reinforce effects of Geosynthetic as a result of the general study on embankment reinforced Geosynthetic. But It is necessary to study variously on each spot condition to apply for Geosynthetic at the several practical field. Also, It is noted to study of effective installation of Geosynthetic on ground condition as well as tensile strength. This study was performed to analyze the stability through Limit Equilibrium Method on embankment reinforced with Geosynthetic. The applied soil parameter described the usual field conditions by applying design parameter used usually at the field. In finally, the influence of Geosynthetic installation and slope angle appeared slightly, but the influence of the depth of soft Ground, Cohesion, and tensile strength of Geosynthetic appeared relatively highly in stability.
