Abstract Based on the literature reviews of the present seismic research on immersed tunnels, four key issues on the seismic design and analysis of ultra-long immersed tunnel with the background of Hongkong-Zhuhai-Macao engineering were addressed: calculation method for dynamic interaction between tunnel segment and surrounding soils, analytical method for seismic response of immersed tunnel subjected to non-uniform seismic loading, seismic mitigation method of immersed tunnel, and shake table test technology of immersed tunnel. These issues will be the focus of further research on seismic design and analysis of immersed tunnel in China.
