摘要

集集地震為台灣百年來引致災害最大之地震。台灣中部地區震度甚大，許多地區，尤其是濱水砂質土壤，發生廣泛的土壤液化現象。彰化縣員林鎮、台中縣霧峰鄉、以及南投市之土壤液化災害最為嚴重，引致房屋受損，橋墩位移傾倒，堤防、擋土牆及水邊結構的崩塌與傾覆以及道路與農田的開裂與塌陷。本文報導在此地區所作之現場調查、鑽孔、現地試驗、室內試驗、以及其土壤液化特性分析的初步結果。此次地震引致土壤液化的資料將被引用為探討台灣土壤液化評估準則之依據。

Chi-Chi earthquake is the most damaging earthquake at Taiwan in a century. The shaking intensities at many places in the central part of Taiwan are very high, and extensive soil liquefaction occurred in many areas. Yuen-Lin, Wu-Feng, and Nan-Tou were especially hard hit with severe damages. Soil liquefaction caused house damages, movements and tilting of bridge piers, settlement and sliding of levees and water front structures, tilting and overturning of retaining structures, and cracking, lateral spreading and subsidence of roadways and farm fields. This paper presents the preliminary results of the field investigation, subsurface explorations, in-situ and laboratory tests, and analyses of the soil liquefaction during Chi-Chi earthquake. The information collected for the soil liquefaction during this earthquake will be used in the study of the liquefaction evaluation criteria for the soils in Taiwan.
