Experimental Study on Seismic Dynamic Characteristics of Shallow-Bias Tunnel with a Small Space

Experimental Study on Seismic Dynamic Characteristics of Shallow-Bias Tunnel with a Small Space

In order to obtain the seismic dynamic characteristics of a shallow-bias tunnel with a small space, a series of large-scale shaking table model tests were carried out. The key technology of the test is introduced in detail, for example, similar ratios of model, test equipment, testing model box, tes...

The key technology of the test is introduced in detail, for example, similar ratios of model, test equipment, testing model box, testing model, sensor arrangement, seismic waves, and testing system. The results show that the first predominant frequency is similar between measuring points. However, the second predominant frequency is highly different between measuring points. The first and second predominant frequencies gradually decrease with the increasing of input PGA. The rock stratum can shield seismic wave in the high frequency band. The research results provide reference for similar tunnels.http://dx.doi.org/10.1155/2018/6412841
