Abstract

With the continuous development of technology, the utilization of underground space is getting higher and higher, and the development of close stacked tunnels is becoming more and more complex and diversified. In this paper, we simulate a close stacked tunnel for an engineering example, and analyze the vibration response of typical measurement points respectively, and derive the vertical vibration acceleration response values of 0.37m/s² and 0.59m/s² for ordinary rail structures under single-line operation and double-line operation respectively, and the vibration acceleration under double-line operation is greater than that under single-line operation under different working conditions. The vibration acceleration under double-line operation is greater than that under single-line operation. At the same time, the ground vibration level of the common rail structure was evaluated without and with the total vibration level, and it was concluded that it did not meet the code requirements, and it was not recommended to use the common rail structure in the overlapping tunnel, and the response vibration reduction measures should be taken if the common rail structure is used.
