Abstract Research purposes: In order to clarify influences of restrictive factors on the ground settlement and up-heal displacement distribution and varying law.
Research methods: Object of shield tunnel test section in a certain city with subway construction in plan was adopted in this paper. With the application of load release factor and equivalent longitude stiffness factor, 3D FEM was carried out in the research of ground sectional groove and longitude settlement curve caused by shield tunnel construction.
Research results: Influences of factors as surrounding soil condition, tunnel bury depth and advance force on the ground movement caused by shield tunnel construction was brought out, 3D curves were also exerted in the discussion of ground settlement space distribution and varying law.
Research Conclusions: Surrounding soil condition illness, tunnel bury depth lessen and advance force enhancement could also result in augmentation of ground settlement and up-heal displacement during construction, suggestions as advance force adjustment during tunnel construction for the reduction of ground environment influences are also brought forwarded in this paper.
