1999年，集集地震袭击了台湾中部，引发了大片地区的山体滑坡。从国家地震工程研究中心进行的野外勘察中获得了大量信息。台湾集集地震岩土灾害调查报告]及其他后续调查。本研究的目的是分析滑坡资料，以评估集集地震引发滑坡的可能性，并据此建立预测模型。分析是在地理信息系统(GIS)环境下进行的，滑坡潜力由Jade和Sarkar[Eng.吉奥尔。36(1993)91]。选取7个因素，用结构方程模型描述各因素之间的关系，建立预测模型。利用一组独立的实地调查数据对模型进行了验证，结果令人满意，实地调查数据显示出较高的潜力。(C)2003 Elsevier Science B.V.保留所有权利。
The Chi-Chi earthquake struck central Taiwan in 1999, triggering many landslides over a broad area. A large amount of information was obtained from the field reconnaissance conducted by National Center for Research on Earthquake Engineering [NCREE, 2000. Investigation Report of the Geotechnical Hazard Caused by Chi-Chi Earthquake, Taiwan] and other follow-up investigations. The objective of this research was to analyze the landslide data for assessment of the potential for landslides triggered by the Chi-Chi earthquake, and a predictive model was constructed accordingly. The analysis was conducted under a Geographic Information System (GIS) environment, and the landslide potential was defined by the information value proposed by Jade and Sarkar [Eng. Geol. 36 (1993) 91]. Seven factors were selected and the structural equation model was used to describe the relationship among the factors and building of the predictive model. Verifications of the model were conducted using an independent set of field investigation data, and results were satisfactory with the field investigation data displaying higher potential.
