.../or high overburden, the ground may greatly deform and the primary support such as steel ribs, shotcrete and rock bolt could be broken. In Japan, multiple-layered support, double or even triple-layered of heavy and strong support, has been applied under such conditions. On the other hand, at tunnel...

... isotope with the increase of the tunnel overburden. The general trend obtained is δ 2 H and δ 18 O decreased with the increase of the overburden. Deviation of the δ 2 H and δ 18 O data from the expected trends may reflect the recharges are coming from the sub-horizontal flow path such as rivers or water...
