中文摘要 | 南投縣鹿谷鄉和雅地區深坑聚落於 921地震後 6年,當地居民於順向坡上方發現裂縫,研判係為受 921地震作用所引起,裂縫最深處達數公尺,其中「六耕」裂縫長約 80公尺。本研究針對和雅地區順向坡進行各項現地調查及資料收集,經由各項調查及分析,探討和雅順向坡受地震影響之滑動潛能,並驗證 921地震對該順向坡滑動之影響。經由地質及鑽探調查與歷年航照判釋分析比對,推測和雅順向坡於深度 60-65公尺處存在可能滑動面,此外,利用擬靜態分析探討可能滑動深度,由鑽探結果之破裂面位置約為 60公尺,與分析結果可能滑動深度頗為一致。因此由各項分析結果可驗證該處順向坡具高滑動潛能。 |
英文摘要 | Six years after the Chi-Chi Earthquake, severe cracks were found in the Herya dip-slope in the Senkern Community, Nantou County, and were postulated being induced by the Chi-Chi Earthquake. The crack in the Liougern area was several meters deep and 80m long. In this research, the potential of the Herya dip-slope landslide induced by earthquake was studied. Field investigations were conducted, and potential analysis was performed using pseudo-static procedures. The possible sliding surface identified from boring logs and topographic analysis was at about 60 meters deep, which appeared to be consistent with the results from pseudo-static analysis. Results of the study verified the high sliding potential of the Herya dip-slope subjected to a similar earthquake. |
