中文摘要 | 本研究依據集集大地震所造成砌石擋土牆、重力式擋土牆及加勁擋土牆之破壞 案例,進行探討並獲得以下結論。公路邊坡擋土結構物可能因地震力作用造成滑移式及傾 覆式破壞。除了動態土壓力外,擋上牆上邊坡受地震力作用向坡腳方向的側向擴張,也可 能對擋土牆的滑移與傾覆造成重大影響。斷層錯動的威力強大,建造於斷層上的擋土牆可 能因斷層的垂直及水平位移而產生嚴重的傾覆與滑移,應避免於活動斷層上建造任何擋土 結構物。 |
英文摘要 | This paper reports failure of gravity walls, masonry walls and reinforced-earth walls related to the 1999 Chi-Chi earthquake. After the earthquake, sliding and overturning failure of retaining structures were observed. The failures were most probably induced by the dynamic earth- pressure and lateral spreading of the uphill slope. A gravity wall built right above the Chelungpu fault was severely damaged by the vertical and horizontal movements Of the fault. It is suggested not to build any retaining structure on top of an active fault. |
