Outline of Final Research Achievements |
In order to conserve the remaining log wooden church buildings in Eastern Europe, this study was conducted to determine the mechanism of slope failure caused by frozen soil, which is thought to be the main cause of damage to these buildings, and to determine the causes of unequal settlement and landslides. Borehole investigations were conducted on the ground on which the wooden church building stands, and monitoring measurements were made using soil analysis and observation wells. The site of the Descent of the Holy Spirit Church in Potelych, Ukraine, had uniform sandy soil and no slip surfaces were identified. The Church of the Nativity of the Holiest Virgin Mary site in Rakowa, Poland is stable, and medium- to long-term monitoring should be conducted to understand the relationship between church building deterioration and ground displacement.

Academic Significance and Societal Importance of the Research Achievements |
東欧の木造教会堂の保存のためには、斜面に立地する敷地の条件を把握して保存対策を進める必要がある。本研究は寒冷地における地面の凍結という気象条件に着目し、地盤工学によるモニタリングを使って地盤の挙動と建物の変形との関連を捉えようとした。このような敷地地盤の状況の科学的把握のためのモニタリングは、職人の経験に基づく修理方法に加えて、客観的に木造教会堂の劣化要因を明らかにする手法を構築することができる。また本研究のモニタリングシステムは、太陽光パネルによる電力供給とモバイルサーバーによる遠隔モニタリングが可能なことを示し、僻地にある文化遺産の環境のモニタリングが可能なことを示した。
