Sažetak
This paper describes numerical modeling of the Kostanjek landslide using the LS-Rapid software. The analyses using the LS-Rapid software were made for two different triggering factors i.e. excess of pore water pressure, and combination of pore excess water pressure and earthquake occurrence, and it was applied at two different landslide cases. In the first case, the LS-Rapid software was used to re- examine the landslide model for the Kostanjek landslide reported by Ortolan (Development of 3D engineering geological model of deep landslide with multiple sliding surfaces (example of the Kostanjek landslide). Faculty of Mining, Geology and Petroleum Engineering, University of Zagreb, Zagreb, 1996), Mihalinec and Stanić (Građevinar 43:441–447, 1991) and Stanić and Nonveiller (Eng Geol 42:269–283, 1996). In the second case, LS-Rapid was used to confirm the Kostanjek landslide model in which the sliding surfaces are initially developed through the soil mass. During the initial shearing, the excess pore pressure is often generated during the landslide activations by triggering factors and the post failure-motion of the landslide. The strength parameters used in these analyses were derived from tests in undrained ring shear apparatus carried out by Oštrić et al. (Proceeding of the 10th anniversary of ICL, Kyoto, Japan, 2012a, Disaster Prevent Res Inst Annu B 55:57–65, b). It is expected that the results of the Kostanjek Landslide simulation using LS-Rapid software and parameters obtained from undrained tests carried out in ring shear apparatus would give realistic results and would help for better understanding of the Kostanjek landslide behavior.
