Settlement Predictions of The Noordtunnel: A Numerical Simulation

The Noordtunnel is an immersed tunnel open to roadway service since 1990 in The Netherlands. Over the past thirty years of its operation time, a significant differential settlement behaviour has been observed, and this ongoing settlement potentially imposes safety concerns to the tunnel, such as joint leakage. However, the underlying factor...

Probabilistic analysis of immersed tunnel settlement using CPT and MASW

Settlement data of the Kiltunnel and the Heinenoordtunnel show that immersed tunnels in the Netherlands have been experiencing much larger settlement than expected when designing the tunnels causing cracks in the concrete and leakages in the joints. Settlements of 8 - 70 mm have been measured at the Kiltunnel and of 7 - 30 mm at the...

Reciprocal Impacts of Land Settlement and Jakarta Rail Tunnel: Numerical analysis of MRT Jakarta North-South Line Phase 2

Significant development of Jakarta infrastructure is necessary to keep up with the economic growth. For the new Jakarta underground rail network, imminent extension of the North-South Line Phase 1 (NSL-P1) tunnel heads towards the northern part of city. One of the engineering challenges that exist in the area is the substantial amount of...

Building response to tunnelling- and excavation-induced ground movements: using transfer functions to review the limiting tensile strain method

In this paper, limiting tensile strain method (LTSM) is reviewed, and advantages and disadvantages resulted from the simplicity of this method are examined in the light of the findings of the existing experimental and numerical studies. Using the viewpoint of the transfer functions for the LTSM, a more independent sight for the interpretation of...
