摘要

國立宜蘭技術學院經德大樓長期監測始自八十二年起至八十五年止共三年，為一國科會四年整合型計畫中之子計畫，其間分年之量測結果已陸續刊登於各年度成果報告中。本文將此三年量測結果予以整合及討論，可因此對一座落地於震區之大型學校大樓結構改變狀況有所了解。至於監測項目以採定期量測之現地測量方法，現地量測工作分為兩項，即〈一〉大樓水平傾斜量及〈二〉大樓垂直沉陷量；兩項量測工作分兩組人員每月進行一至二次量測，每年內所量測次數也約略相同，各項量測時所使用經緯儀，水準儀及標尺之種類及準確性均經有定期檢驗以確保量測之精度。

The research involves the investigations of inclination and settlement of the school building which is located at the campus of the National I-Lan Institute of Technology. During a period of three years, two different teams of members respectively measure the amounts of inclination and settlement one or two times in each month. By observing the recorded data for each surveying point set up for the building, it is found that the maximum single record of inclination is 0.9 cm and the maximum calculating value of cumulative inclination is 0.8 cm. In the mean time, it is also noted that those values of inclination change the sign frequently. On the other hand, the maximum determined value of settlement is 2.1 cm and the maximum final value of cumulative settlement is 0.9 cm. Both valuse of the maximum calculating cumulative inclination and settlement are within 1.0 cm. On the basis of considering various errors, these small amounts of inclination and settlement may indicate that the building remains the same level of position without variation. As a final, some issues related to the methodology of field setup for this study as well as recommendations for future studies are also reported in this paper.
