摘要

Base on arbitrary Lagrangian-Eulerian(ALE) method, three dimensional finite element model for steel extension in shield machine butting was established. The problem of mesh deformation distortion caused by soil flow deformation was resolved, while tube-soil dynamic coupling process was realized. Resistance change and stress-strain conditions of steel tube during the extension was analyzed. Simulation of steel tube extending under different velocity was processing. Axial and lateral stability of steel tube was researched, mainly considering contact and gravity status. The results provided the reference for the design of shield butting construction.
