In order to meet the high demand of sophisticated and accurate calculation model,rational evaluation of loads caused by complex construction circumstances,multiple structure and functions,the computing methods of loads in recent shield tunnel design were reviewed by investigation and survey,and the static and dynamic analysis methods and calculation models on the basis of related researches in the past 10 years were summarized.As to the parameters of loads,problems and the development of the mechanism of water and earth pressure in the deep space,the fluid-solid coupling effect and the reasonable parameters of seismic loads in rocks were discussed.As for calculation theory and models,this paper focused on the main points of holistic analysis method of shield tunnel.Whilst the recent achievements in mechanic behaviors upon complex joints＇ interface of shield tunnels,analysis method based on non-liner iterative algorithm of joints bending stiffness,integral mechanical characteristics and failure modes of shield tunnels evaluated by experiments and in-site measurements were introduced.Furthermore,taking seismic deformation method of ground-structure continuum mode and generalized longitudinal seismicdeformation method as representatives,the achievement of anti-seismic analysis in transverse and longitudinal direction was summarized.The recent research on the structural analysis of shield tunnel was introduced,taking durability into account.Finally,considering the application prospect of shield tunnel constructed in deep space,under high water pressure,or in specific circumstances,this paper provided an outlook of the developing trend of shield tunnels structural analysis.
