Utsunomiya City is located approximately 100 km north of Tokyo. The prefectural capital city of Tochigi prefecture is famous for 餃子in Japan. The city is also famous for mining 大谷石(Oya tuff or Oya stone) as stone materials from the underground quarries. The stone materials are mainly used for building retaining wall and decorating buildings. After mining those stones, many underground spaces have occurred in narrow area in Oya town for over 100 years. Almost quarries have abandoned and some of them are re-used for sight-seeing places. As Oya tuff is categorized as soft rock, it is easy to produce the building goods, but to weather easily. So sometime it is problems to use for long time. Based on the background of Oya underground quarries and Oya tuff, the speaker and his research grope focused on studying the factor of weathering process of Oya tuff and the structural stability assessment of the underground quarry for re-using the spaces. In this talk, the speaker will present those trials. He welcomes idea and cooperative possibility from the audiences.
