�@Interaction between ground and tunnel behavior is not clear, because the mechanism is very complicated. We measured about earth pressure, water pressure and sectional force acting on tunnel lining, at an in-situ slurry shield driven tunnel in dilubium deposit. Then, we investigated the design load on tunnel lining.
�@Overbarden at measured point is about 19m. Segments are corrugate type made of ductile cast iron and they are 350mm in height and 1,000mm in width.
