Description

This study aims to preliminarily evaluate the earthquake-resistant performance of ILC tunnel and large cavern excavated into good-quality granitic rock masses around the potential Kitakami site of ILC in Japan. Even though tunnels in good rock is not required to consider earthquake effects (JSCE standard), ILC underground facilities should roughly be checked quantitatively and 2D analyses with using SuperFLUSH (dynamic FEM) are performed in this paper. Also, the image of tunnel support damage level at earthquake for ILC is discussed here. As a result of numerical analyses, ILC tunnel support and large cavern shotcrete are evaluated to keep sound when they are hit by the Level 2 earthquake input wave, which is the strongest earthquake in history.
