The first quasi rectangular shield tunnel in China was developed during the construction of Ningbo Metro Line 3. Based on the Mindlin solution, this paper presents the computerized outcome of the ground surface deformation caused by the following three factors: the hirizontal excess pressure at the exavation face, the frictin between the shield skin and soil, and the grouting force outside the …
The deformation and stress of a super-large-diameter shield tailskin are analyzed in this paper. Four kinds of structure analysis models, i.e. the perfect solid shell model, the defected solid shell model, the perfect hollow-layered shell model, and the defected hollow-layered shell model are formed to study the effects of initial geometrical defects and the hollow-layered shell formation on th…

Immersed tunnel is already a major underwater construction and the stability analysis of immersed tunnel is of great significance in marine engineering. Most previous investigations of the immersed tunnel are about seismic response and did not consider soil anisotropy. In this paper, we developed a 2D model to discuss the effects of soil cross-anisotropy on the residual liquefaction around an…
The Complicated-long Tunnel, with high uncertainty of factors such as geological and environment conditions, may cause major challenges in the design and construction process. Specifically the static data of geological exploration based on traditional design and construction can’t meet the requirements of refined structure design and construction control. Aimed at more refinement services for…
