Abstract:

During tunnel excavation, a variety of geological disasters might be encountered, such as faults, caves, et.al. Tunnel seismic prediction (TSP) is adopted to mitigate the possible damages. Although TSP technology is used widely, the research about TSP is currently focused on its engineering application cases. We use the finite element method to simulate the tunnel seismic wave field, employ wave field snapshots and time recording method on the impact of faults on the characteristics of the propagation of tunnel seismic wave field, and inversely process the time record of model containing the fault. The digital model of the velocity scattered image and the reflection interface position are obtained, and the fault position from velocity scattered image processed with the default values set by using TSPwin is agreed to the one from the model. In respect to the layered model for an abnormal velocity zone, P-wave is more precise. The system of TSP is strong for its feature of anti-noise. The numerical simulation is verified finally through the process and analysis of the engineering cases.

Key words: TSP, TSPwin, snapshot, tunnel seismic prediction, fault
