Abstract The railway in Indonesia is in the development phase, which began with
the construction of new railway lines including railway tunnels. On the other hand,
Indonesia is located at the “ring of fire” zone with dense geological structures due
to the subduction process. The subduction process increases seismic and volcanic
activity. This becomes a hindrance for tunnel construction. Seismic activity has the
potential to form geological structures while volcanic activity affects the formation
of sedimentary rock mass properties. Both of these processes affect rock mass qualities
which are described by the RMR parameters. The geological structures in the
sedimentary rock will accelerate the weathering process. Weathered rock layers and
minor fault appearance are important issues to be considered in the constructions
of railway tunnel. This research aims to simulate a horseshoe tunnel model that
considers dynamic load on weathered rocks in evaluating tunnel stability and durability.
The dynamic load from the subduction zone is calculated using the point source
method to estimate the dynamic load affecting the tunnel. In this study, the model uses
plain strain idealization with numerical methods to yield a real condition approach.
The model analysis is made with Rocscience software by taking into account weathered
rock and arching effect. The result shows that subduction activity increases
the dynamic load on weathered rocks that will affect tunnel stability and durability.
This seismic performance evaluation is an essential study in tunnel construction
performance in the future.
