中文摘要 | 台灣的地質條件脆弱,處在環太平洋地震帶上,夏季經常受到颱風侵襲,高聳的山區地形受到強烈的風化作用影響,使山區邊坡容易發生崩塌或是地滑,而近年來氣候變遷加劇,更加深了此影響;然而多處崩塌地因位處偏遠,若派遣人員進行調查,一來費時冗長、成本昂貴,且蒐集資料有限,同時具有一定的危險性,而採用衛星影像則有可能忽略實地狀況與解析度不足等缺點。故本研究將探討運用的無人飛行載具進行邊坡調查之可行性。 無人飛行載具(Unmanned Aerial Vehicle, UAV)近年來被廣泛運用於各類的災害調查及防災監測,由於具有重量輕、體積小,機動性及安全性高、維修容易且成本低廉,可在高風險區域執行調查任務。搭配技術純熟的航空攝影測量,將進行調查之空拍影像以控制點接合後,可再製成數值地表模型(DSM)以及正射影像圖,且精細度可以達到5公分,若是邊坡發生破壞前的潛變行為,亦可由不同時序測量結果而發現。 本研究將無人載具初步應用在南投縣仁愛鄉人止關台14線75K處及台18線阿里山五彎仔,此二處邊坡發生破壞後有再度崩塌的案例出現,對於是否會造成更大災害仍須審慎評估;本研究以無人載具進行邊坡調查,搭載三軸向可控式雲台,以不同角度進行崩塌地拍攝,將拍攝結果製成DSM與正射影像,最後以FLAC/slope進行邊坡穩定分析,日後可供工程規劃參考,並持續追蹤邊坡變化情形。 |
英文摘要 | Geological condition of Taiwan is fracture with locating on Pacific Rim seismic area. Typhoons usually attack during summer and steep mountains are highly weathered, which induces landslide in mountain area. The situation happens more often recent years due to heavy weather change. However, most landslides are very far away. Field investigation is time consuming, high budget, limited data collected and dangerous. Investigation with satellite images has disadvantages such as less of the actual situation and poor resolution. Thus the possibility for slope investigation with UAV will be discussed in this research. Hazard investigation and monitoring is adopted UAV in recent years. UAV has advantages such as light weight, small volume, high mobility, safe, easy maintenance and low cost. Investigation can be executed in high risk area. Use the mature aero photogrammetry , combines aero photos with control point. Digital surface model (DSM) and Ortho photos can be produced with control points aligned. The resolution can be less than 5cm thus can be used as temporal creeping monitoring before landslide happens. Three large landslide sites, 96k at highway Tai-8, 75k at highway Tai-14 and Wuwanzi at highway Tai 18 are investigated in this research. Landslides happened in these sites. Further landslides could be happened in near future. Thus UAV with tri-axial servo cradle head is used in this research performed photography with different angles. The results have been produced DSM and Ortho photos for Finite Difference Analysis, which can be reference to engineering design and keep tracking landslide deformation behavior. |
