Abstract:	摘要： A large and deep-seated landslide at Hungtsaiping was triggered by the 1999 Chi-Chi earthquake with the magnitude of 7.3. Extensive site investigations for the landslide were conducted including field reconnaissance, geophysical exploration, borehole logs, and laboratory experiments. Thick colluvium was found around the landslide area and indicated the occurrence of a large ancient landslide. The Hungtsaiping area involves at least two large landslides events, an ancient rockslide and the 1999 colluvium slide. With the consideration of a source collapse mass, the two landslides in sequence are reasonably reproduced by the distinct element modeling. The modeling is calibrated by rock mass strength behavior through a procedure with the Hoek–Brown failure criterion, statistical experimental design, and optimization techniques. The mechanism of the 1999 landslide that cannot be revealed by the underground exploration data alone is clarified. The proposed procedure enables a rational and efficient way to determine micro-parameters for the distinct element modeling of landslides. 其他題名： Landslides 出版者： Berlin/Heidelberg: Springer-Verlag 出版日期： 2012-06 出處： Landslides, 2012-06, Vol.9 (2), p.205-214 資源來源： Agricultural & Environmental Science Collection 版權： Springer-Verlag 2011 版權： Springer-Verlag 2012 識別號： ISSN: 1612-510X 識別號： EISSN: 1612-5118 識別號： DOI: 10.1007/s10346-011-0293-5
