中文摘要 | 高鐵計畫與其他交通建設在大地工程設計最大的不同除了載重條件之外,較為嚴格允許變位量是主要的特色。但是從營運安全的角度來看,如何降低營運中高鐵結構面臨地質災害所帶來的風險,反而是大地工程考量的另一個的重點,高鐵沿線可能發生的地質災害包括地震、暴雨及斷層錯動造成的邊坡問題、以及彰雲地區地層下陷問題,本文將要討論這些地質災害對高鐵的影響,以及為降低這些地質災害帶來的風險所採取的措施。 |
英文摘要 | Comparing with other transportation infrastructures such as freeway and MRT, the geotechnical engineering design for high-speed rail project adopts similar principles except different loading conditions, higher safety factor, and more stringent allowable displacement of foundation structure. However, from operational safety point of view, minimizing the impact from natural geological hazards along the railway alignment becomes a critical issue. This paper will first review the natural geotechnical hazard along the HSR alignment. It has been identified that slope instability associated with heavy rainfall, earthquake and active fault movement, and ground subsidence are the three key natural geotechnical hazards. The actions including monitoring, inspection by professional geotechnical engineer and geologist, engineering assessment, and building up the early warning system have been taken to ensure the railway operational safety. |
