中文摘要 | 本文除對這次莫拉克颱風引發之高屏地區邊坡崩塌勘查資料作彙整報導外,並透過這次颱風期間之降雨入滲、雨水滲流、地下水變動、地層孔隙水壓變化及地層位移之模擬成果,探討完整之水文地質穩定分析案例。勘查路線包括高雄縣旗山溪與荖濃溪流域,主要道路則有台20、台27、台27甲線、高128及高130縣道。災害類型主要包括:道路與河岸邊坡崩坍,另有多處大型土石崩落與土石流災害。案例分析部分係以經濟部中央地質調查所委託中興工程顧問社於寶隆崩塌地(高128縣道)案例為例作說明,此案例透過詳實之現地鑽探、調查與試驗成果建置水文地質概念模型,再以GeoStudioTM進行模擬分析,模式分析之正確性係透過現場監測值進行驗證。驗證成果顯示此模式已可擬合颱風前之常時水位且掌握莫拉克颱風期間水位抬升的型態,進而可評估其穩定性及變形性。 |
英文摘要 | This paper present the field exploration of the hazards of rainfall induced landslides by the Typhoon Morakot in Kao-Pin area, and the hydro-geological numerical simulation analysis for an integrity monitoring case study on the infiltration, seepage, groundwater variation, pore water pressure change and displacement of the slope land. The exploration routes are along the Chishan river and Laonong river watershed in Kaohsiung County. The main routes included are Route 20, Route 27, Route 27 A and county road No. 128 and No. 130. Type of disasters include: the landslides along road and river banks, and several large-scale rock falls and debris flows. The case study presented refers to the project on the landslide site of Baolong near to the local road No. 128, which was conducted by Sinotech Engineering Consultants Inc. and commissioned by Central Geological Survey, MOEA. For the numerical analysis, the program GeoStudioTM was used, and SEEP / W, SLOPE / W and SIGMA / W modules are applied. An integrated field investigation and test results, as well as on-site monitoring value are used and comparisons are made. The results show that the model of analysis fits the lifting state of water level in the period of typhoon Morakot. Furthermore, it may also appraise the performance of slope stability and deformation. |
