中文摘要 | 士林水力發電工程電廠基於水力落差及地質等因素,設於鯉魚潭水庫上游之景山 溪右岸山腹。該處岩層雖強度較低,膠結不佳,但節理不發達,大玫呈勻質完整且無明顯地 質構造,仍不失為一適合的廠址。然廠房通道及廠房開挖時,曾遭遇湧水及剪裂帶等惡劣地 質,前者經加強抽排水及支撐、探查導水,並於湧水處接管強制抽除,費時一個月予以克服 ;後者以先撐環挖及灌漿等保護方式得以通過。其後考量廠房施工困難度、工期、成本及長 期安定,設計上作廠房位置變動以避開剪裂帶,終能繼續施工,預期能安全順利完工。 |
英文摘要 | Based on the consideration of water head and geology, the powerhouse of Shihlin Hydropower Project was located in the underground of the right bank of Chin San Creek at Chin San. However, bad geological conditions including gushing groundwater and shear zone were encountered during excavation of the access tunnel and powerhouse. It took one month and half a year separately to teat the above said geologic hazards. In considering the safety of powerhouse structure, a design change of relocation of powerhouse covern was made. At present, the construction is going on smoothly. |
