Abstract EN
The metro tunnel lines built in a soft soil area may suffer from tunnel differential settlement due to the high compressibility of soft soil, the engineering constructions nearby tunnel lines, and the cyclic load of metro trains.
In this paper, a dynamic coupling model for a metro train-monolithic bed track system under tunnel differential settlement is established.
A cosine function is introduced to simulate a real settlement curve measured from a metro tunnel in southern China, and the vibration performance of the train-track system under tunnel settlements is investigated in both the time domain and frequency domain.
Based on the standards for the train safety and passengers’ comfort, the speed limit for the metro train traveling on a monolithic bed track with different settlement distributions are concluded.
The present research could be useful for the operation and maintenance of metro tunnels in soft soil areas.
