“…One of the most well-known reasons for earthquake-related ground movement and failure is liquefaction [1]. Following liquefaction during earthquakes, the common geotechnical phenomena are the settlement and lateral spreading of saturated soil deposits [2]. These phenomena lead large soil movement, inflicting extensive damage to underground utilities, vital networks, and a variety of other subsurface and surface infrastructure like buildings, toll roads, bridges, embankments, dams, etc.…”

The common phenomena during liquefaction are the lateral displacement and settlement of saturated soil deposits. These phenomena have the potential damage to the toll road construction where this research is taking place. Toll road projects in Mungkid and Candimulyo Districts, Central Java, Indonesia must be evaluated for lateral displacement and settlement. The study area is located in volcanic deposits originating from Mount Merapi and Merbabu, with shallow groundwater level in some location, and a history big seismicity. PGA value at the research location was calculated using webpage application from Lini Binamarga. This study aims to calculate liquefaction severity using LSI method, lateral spreading using LDI method, and the ground settlement using reconsolidation settlement method with various moment magnitude scenarios. LSI in Candimulyo and Mungkid District are 17.77 (low severity) and 9.68 (very low severity), respectively. Candimulyo and Mungkid Districts experienced the greatest lateral spreading of 3.84 m and 1.87 m. Also, Candimulyo and Mungkid Districts have the largest settlement by 0.42 m in the extensive damage category and 0.15 m in the medium damage category. Based on this assessment, it is necessary to investigate the mitigation required to reduce lateral spreading and settlement caused by liquefaction.

“…The results, along with detailed raw data, were published by the Japan Geotechnical Society (2009). Tsukamoto and Ishihara (2010) revised their original procedure for evaluating post-liquefaction settlement by referring in part to the results of the investigation in Ansei-cho in Kashiwazaki City. This paper reports the relationships at various housing sites based on victim interviews, direct visual inspections of liquefaction traces and structural damage, subsurface explorations such as in situ soil investigations utilizing Swedish Weight Sounding (SWS) tests and Standard Penetration Tests (SPT), old topographical map examinations, etc.…”

The 2007 Niigata-ken Chuetsu-oki (OŠ Mid-Niigata) earthquake caused the liquefaction of the sandy soil distributed near the coast of the Japan Sea in the middle of Niigata Prefecture. The liquefaction-induced damage occurring in many residential areas was investigated in detail by means of victim interviews, visual inspections, Swedish Weight Sounding tests, Standard Penetration Tests, old topographical map examinations, etc. Based on in situ soil investigations, the liqueˆed soil layers were estimated for each area. As a result, it was conˆrmed that the liqueˆed areas were mainly sand dune hinterlands, ‰ood plains, reclaimed old river channels and sandyˆlls with high groundwater table. Among them, damage was especially serious on land having an inclined ground surface due to the ‰ow of foundations, on the cut-ˆll borders of artiˆcially developed land due to landslides and at the toes of sand dune slopes due to the thrust of the sliding soil and/or the collision of the sliding soil with objects. These investigation results also revealed that soil improvement by cement mixed columns is an eŠective countermeasure against liquefaction-induced damage unless lateral spreading of the subsoil arises.
