Circular Lining Behaviour due to Earthquake Load in MRT Jakarta Underground Tunnel Area CP-106

EasyChair Preprint 3671

Abstract

One solution to congestion in Jakarta is to build a Mass Rapid Transit (MRT), a special application for subway structures. This study calculates circular tunnel behavior in static and dynamic conditions due to earthquake effects. Static condition analysis using Muir Wood's theory and dynamic conditions using the theories of Wang (1993) and Panzien (2000). The depth of the MRT tunnel in the CP-106 area is at a depth of 11 meters by diverting by clay with NSPT 3-20. The results show that in static condition has tunnel deformation that works at 8.06 mm. In the dynamic analysis with earthquake acceleration in 0.359 g produces oval deformation at 15.95 mm. The maximum deformation limit given is 20 mm with a maximum earthquake acceleration value of 0.4 g. In conclusion, MRT Jakarta area CP-106 in static condition has a lower deformation than dynamic conditions, but both conditions fulfill the deformation tunnel requirements.
