Abstract
The construction of toll roads in Klaten Regency supports community connectivity in increasing economic growth and accessibility to tourist areas around the southern part of Java Island. The location of this study is in Polanharjo District, Klaten Regency. The study area has geological conditions, sandy volcanic ash, and shallow groundwater levels and is accompanied by a history of earthquakes that have occurred greater than Mw. 5.0. These three things are triggers for liquefaction. This study discusses the stability analysis of toll road embankments at the STA. 10+724 on the construction of the Solo - Yogyakarta - YIA Kulon Progo Toll Road due to the potential for liquefaction reaching 14 meters. The road embankment construction is placed on the ground surface, which has the potential for liquefaction with a height of up to 5 meters. Calculate the safety factor using the numerical simulation finite element (Plaxis v.8.2 software) with static and pseudostatic analysis. Numerical calculations show that the stability analysis of toll road embankments placed on the ground with the liquefaction potential is still safe for construction with a safety factor on the static analysis (SF: 1.989 > 1.5) and pseudostatic analysis (SF: 1.912 > 1.1).
