Method for analyzing seismic response of shield tunnel and its application
摘要
Abstract
Seismic load can bring serious damage to shield tunnel. Reasonable seismic analysis of tunnel can help to reduce or avoid potential seismic hazard. So it is necessary to establish efficient model for seismic response of shield tunnel. Segment connectors are simulated by embedded beam elements, and segments are simulated by thick shell elements. At the same time, noncontinuous contact is built between segments and between segment and surrounding soil, which can better simulate stress in thickness direction and the interaction between segments. Thereby, the thick shell-contact-infinite element model for dynamic analysis of shield tunnel is built. Actual seismic disaster data and project results prove that the model has good accuracy. Finally, the model is used to analyze grouting material parameters and contact nonlinearity on the impact of seismic response of segments. This model has a good popularization value for seismic disaster analysis of shield tunnels or tunnels constructed by TBM.关键词
