Tsaoling landslide is the largest and best documented among several large landslides induced by 1999 Taiwan Chi-Chi earthquake. Pliocene sedimentary rocks of about 125 Mm3 in volume slid along very flat bedding planes dipping 14° with an average speed 35–40 m/s for 1650 m, before hitting bank Chinshui River during landslide. Detailed analysis DTMs after earthquake using a GIS software leads to accurate determination locations centroids mass, revealing horizontal vertical displacements 2524 m...
Pliocene sedimentary rocks of about 130 Mm3 in volume slid along bedding planes dipping by 14°, with an average speed 35 m/s, during the Tsaoling landslide. We conducted friction experiments to reproduce initiation processes this landslide, idealizing landslide movements earthquake as accelerating/decelerating motion. Experiments were done on shale from field, at 3 MPa normal stress corresponding overburden pressure. Results indicate that motion causes weakening and strengthening each...
The critical taper model has been widely used to evaluate the strength contrast between wedge and basal detachment of fold-and-thrust belts accretionary wedges. However, determination parameters using traditional model, which adopts Mohr–Coulomb failure criterion, is difficult, if not impossible. In this study, we propose a modified that incorporates non-linear Hoek–Brown criterion. in proposed CHBW can be directly evaluated via field investigations laboratory tests. Meanwhile, function...
