中文摘要 | GPS/GIS/RS科技整合應用於大地工程災害之調查研究,於國內尚屬萌芽,由於其 可對各類災害資料作即時性提供與快速整合統計分析,不但有利於資料之儲存建檔分析,更 有利於後續資料之更新擴充與自動萃取,故極具便捷功能。近年來,由於台灣各大都會區之 擴張,使得都會區邊緣之山坡地均因人為開發活動頻仍,而造成各類大地工程災害,故本文 乃以大高雄都會區為例,應用GPS/GIS/RS之科技從事於高雄地區大地工程災害之調查分析。 近年來大高雄都會區所發生相關大地工程災害為數不少,如岡山之泥砂水患,旗山孔廟之地 層滑動與基礎陷落,花旗山莊之邊坡滑動,六龜茂林風景區之溪流淘刷災害,壽山與柴山地 區之地層滑動,及田寮燕巢泥岩地區之坡面沖蝕災害等均屬之,此對未來南台灣地區之經建 發展影響至鋸。有鑑於此,本文遂首先引用遙測衛星影像處理和航照判釋技術,將高雄地區 依其坡地開發活動頻度,災害發生特性及主要岩層特徵劃分為北(旗山地區),中(岡山地 區)及南(楠梓地區)等三地區,並先以旗山地區為重點,完成旗山地區之各項相關基本資 料圖層,且研判其環境地質破壞、邊坡崩塌與土石流/泥流等三項大地工程災害分佈地區, 據以建立旗山地區因坡地開發所衍生之大地工程災害資料庫,同時配合賀伯與溫妮兩次颱風 之侵襲紀錄,以GPS/GIS/RS整合科技作現地災害調查與災害特性及發生主誘因研判分析,獲知 旗山地區之大地工程災害大多發生在海拔100∼140m間之淺山丘陵地,地質大多屬南化泥岩 層,土壤則以中至細顆粒之低塑性粘性土壤(CL)為主,且以坡地 |
英文摘要 | The disasters of geotechnical engineering occurred at surrounded metropolitan in Taiwan such Kaohsiung areas, have not only been recognized as a problem today but also a serious concern by the public in the furture. Weak geological structure, unevent distribution of rainfall intensity, steep geomorphology and high intensive human activity have been identified as the predominated factors contributing to the geotechnical engineering disasters frequently occurred at Kaohsiung area. The natural hazard and disasters which damage to property and human life can be severe through whole Kaohsiung metropolitan area. Large scale mass movements and geoenvironmental disasters observed from satellite photography on the surface of earth should be required for this study. The applications of geograhic information systems (GIS), remote sensing (RS), image processing and aerial photography identification integrated with computer aid design (CAD) and relational database system (RDBS) would be necessary for this research. Chyi-Shan area located at the north of Kaohsiung city would be selected as an experimental site in this research. The attribute data combined with the characteristic map and developed from ARC/INFO system has been conducted and analyzed by using GPS/GIS technology and image process of RS. The southern aspect of hillslope with the 40°∼ 70°of slope steepness at the elevation between 100 and 140 meters in this area would be identified as the most serious geotechnical engineering disaster areas. It is expected that the establishment of geotechnical engineering database systems can be fully structuralized and to be used to help the planning of hillslope development, hazard mitigation of slopeland and public engineering construction on Kaohsiung metropolitan area in the southern Taiwan. |
