Settlement Analysis in Potentially Liquifiable Soil at Kretek 2 Bridge Area

Abstract The Kretek 2 Bridge is one of the important infrastructures built on southern coast road Java. Referring to Map Indonesia Liquefaction Vulnerability Zone in 2019, was identified as a high liquefaction susceptibility zone. result potential analysis slab-on-pile section indicates that soil layer has liquefy if an earthquake occurs. Based Severity Index, severity index at BH-10, moderate BH-11, and low BH-01 BH-12. One effects ground settlement. Settlement due vertical deformation caused by compaction earthquake. This study conducted calculating settlement sand deposits using equation proposed Zhang et al. 2002 Yoshimine 2006. results Zhang’s method predict area, BH-10 having most significant 29.803 cm. Using Yoshimine, highest found which 30.401
