Abstract: Based on a certain multiple arch tunnel project, the magnitudes and distributed regularities of stratum displacements have been attained through the numerical simulation analysis for the whole construction process of 40 m-length entrance section using 3D FEM, which is proved and given some necessary supplements through model test with the natural scale of 1:20. Therefore, the stratum displacements regularities and the key-attention zones during the whole construction process are put forward, which will have the direct guidance for the actual engineering works and reference for the similar project as well.

Key words: multiple arch tunnel, stratum displacement, 3D FEM, model test
