Structural Behavior Under Construction and Effects on Surrounding Environment Control Through Instrumentation Monitoring on MRT Project Jakarta
摘要
This study is done on MRT CP-X located from Thamrin - Monas Area in Jakarta. The Total Length of MRT CP-X railway line is be 1,96 km. At this Location, The Line start down the tunnel with an urban area and heritage building stand above the surface area. Field instrumentation became one of key to the safety and control during and after construction of the urban area construction. During the Construction of tunnel using TBM machines, settlement and Displacement of Tunnel segment are monitored by instrumentation using Extensometer and Laser Distances to prevent any possible damage due to unexpected factors. In conjunction with it, the heritage buildings are installed with tiltmeter and topographic reference for safety and prediction of long-time subsidence effect.
