Evaluation of Transverse Seismic Calculation Methods for a Circular Tunnel in Soft Soil
Abstract: Tunnel has been applied widely in the world's major underground transportation engineering. In recent years, earthquake disasters frequently occurred in whole world, such as Kobe earthquake in Japan in 1995 and Wenchuan earthquake in China in 2008, caused damage to underground structure facility. Therefore, seismologists around the world pay attention to seismic studies of underground...

Longitudinal Rigidity of Shield Tunnels Based on Numerical Investigation
Abstract: In recent years, shield tunnelling method has been widely used in world’s underground transportation engineering due to its high mechanization and mature technology. However, according to past researches, slender structures as shield tunnels are particularly sensitive to differential settlement of foundation, which may lead to large opening of the segment joints and consequently complete...

The Influence of Layered Soil on Dynamic Analysis of Underground Structure
Abstract: Statistically speaking, underground structures experienced a lower rate of damage than surface structures. Nevertheless, in the wake of vast construction of underground facility, i.e. subways, underground emporiums and pipelines, some underground structures have experienced serious damage during recent large earthquakes. Consequently, varies of methods for seismic design and analysis of...
