Design Method of Pipeline in Shield Tunnel against Fault Displacement
In this paper, we report a calculation method and calculation example of a fault countermeasure pipeline in a shield tunnel built with earthquake-resistant ductile iron pipes (ERDIPs). When a pipeline is installed in a shield tunnel, it is necessary to consider the interaction between the ground and shield tunnel, the shield tunnel and tunnel backfilling filler, and the filler and pipeline. Therefore, the pipeline performance against fault displacement was evaluated using a composite pipeline model to simulate the pipeline, shield tunnel, ground, and tunnel backfilling filler. We propose a method for designing a pipeline subjected to fault displacement based on the analysis results of the composite pipeline model. The use of a collar or long collar effectively improved the performance of pipelines against fault displacement.
