シールド掘進による地盤の剛性低下と作用土圧
Preserved Fulltext
Earth pressure to act on a shield tunnel depends on size of stress release of the ground caused by shield driving. And size of the stress release depends on ground rigidity. Accordingly it becomes important to evaluate these two factors adequately in order to calculate earth pressure. Therefor analysis model of three dimensional non-linear elastic FEM, which can evaluate a process of stress release and ground rigidity, is proposed. Ground rigidity and earth pressure to act on a shield tunnel is
