Banda Aceh is surrounded by the subduction of Indo-Australia and Eurasia plate which may cause the tsunami. One of it was the tsunami which occurred in Aceh on December 26th, 2004. The governments lack of preparedness for temporary evacuation sites in the high risk disaster zone caused the large number of casualties. Hence it is necessary to build evacuation facilities such as escape hill. The objective of this research is including to determine the bearing capacity of the soil subgrade below escape hill soil embankment and settlement, due to the load of the embankment height (Hcrit) and the value of the safety factor. This study is conducted in Deah Baro with the Geographic Coordinate System(GCS) 5º3345.72"N - 95º1751.34"E. The calculation method of Hcrit in this study was conducted by using Plaxis 8.2, which started from the existing site to 15.00 m or higher than Tsunami run-up wave height 12.00 m. This study uses soil parameters variation modeling by increasing the soil cohesion value (c) and soil friction angle (φ) proportionally with simulation to get stable condition by safety factor (SF) greater than 2.5. The result of this research found that the soil subgrade settlement δ=17.45 cm with SF=1.04 that is less than 2.5, which is still within in the tolerance limits and the subgrade is still able to withstand the embankment load. As the last result, the most stable condition at Hcrit =15.00 m was obtained in the soil parameter modeling with the c =1.5 kN/m2 and φ = 30º, with δ = 15.96 cm and SF= 1.33 which can be used for the escape hill design material embankment.
