Research Interests
Tunnel and underground space laboratory have two types of research tasks. One of them is a type of basic and fundamental subjects for practical works. These studies are divided into two groups to pursue. One is performed in cooperation with external organizations, and the others perform as graduation theses, master's theses and doctoral theses. on each study. In addition, we have enhanced our recognition for practical affairs by providing laboratory students with opportunities to experience construction sites in the real world several times in a year.
