Experimental study on seismic response of subway station built in loess

“…Several researchers have conducted centrifuge shaking table tests on one-story and three-span subway stations, circular tunnels and one-story and two-span subway stations respectively, and the disaster mechanism of underground subway structures during earthquake was revealed by the series model tests (Han, 2011;Ling et al, 2012;Wang et al, 2013). Tsinidis et al (2013) analyzed the seismic response of square section tunnel in sandy soil by centrifuge shaking table model tests, which indicated the swaying movement pattern of the tunnel in earthquake. In addition, some researches have been conducted to investigate the upward movement of model structure buried in liquefiable sand soil by centrifuge shaking table tests (e.g., Koseki et al, 1997;Sasaki et al, 1999;Adalier et al, 2003;Tobita et al, 2011;Chian and Madabhushi, 2012;Lanzano et al, 2012;Kang et al, 2014).…”

Numerical Modelling of the Behavior of Tunnel in Soft Surrounding Rock: A Case Study of Djebel El-Ouahch Tunnel, Algeria

“…The soil structure interaction effects are closely related to the interface characteristics between the structure and the surrounding soil. They are expected to be increased in cases of non-circular (i.e., rectangular) embedded structures (Tsinidis et al 2013). According to M. Patil and al.…”

Shaking-table tests and numerical simulations on a subway structure in soft soil

“…These works could expand our knowledge on seismic performance of different types of cross section subway structures. In terms of numerical simulations, several methods are available in the literature for the evaluation of the seismic response of underground structures [15][16][17][18][19][20][21][22][23][24]. For instance, Huo underground structure and the surrounding soil and to identify the causes for different behaviors of similar sections of the Daikai station subjected to the same seismic loading [15].…”
