清木隆文（Takafumi SEIKI），博士，日本國立宇都宮大學教授、博士生導(dǎo)師。1994年畢業(yè)于名古屋大學，獲工學博士學位，曾任英國帝國理工學院（Imperial College London）助理研究員。長期致力于巖體-地下水-熱三相耦合的理論研究，巖體結(jié)構(gòu)的動態(tài)/靜態(tài)穩(wěn)定性評價及地下空間有效利用的研究和推廣；并且將其研究成果成功應(yīng)用于防災(zāi)減災(zāi)、能源儲存及地下工程安全領(lǐng)域。清木教授長期擔任日本土木學會、日本材料學會和國際巖石力學學會及其分會等權(quán)威機構(gòu)的秘書長，積極推動巖石力學領(lǐng)域跨學科的交叉融合創(chuàng)新發(fā)展。主持和參與多項日本國家級科研項目，研發(fā)的巖體穩(wěn)定性評估技術(shù)為隧道工程、深部資源開采及地下空間開發(fā)領(lǐng)域提供關(guān)鍵理論支撐。發(fā)表高水平學術(shù)論文50余篇，參編18部學術(shù)專著及會議論文集。

內(nèi)容簡介：

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.
