Assessment of rockfall hazard around Afyon Castle, Turkey

“…Then the location is chosen for constructing the systems to prevent rockfall. The past studies on the rockfall analysis have been carried out for designing and accessing passive protection methods (Azzoni et al, 1995;Chau et al, 2002;Giani et al, 2004;Topal et al, 2007;Pantelidis et al, 2011;Lambert et al, 2013) and several computer programs have already been developed (Guzzetti et al, 2002;Crosta and Agliardi, 2004;Agliardi et al, 2009;Masuya et al, 2009). However, the trajectory of rockfall, such as bounding height or runout length, is difficult to predict due to the Hoop support cable; 6.…”

Abstract.A new concept of flexible rock-shed is proposed in this paper. The flexible rock-shed is made of flexible nets held up by a specially designed, steel vaulted structure. A 1 : 1 prototype is manufactured and tested for functional evaluation with an impact experiment. It is shown that the structure can stand for an impact energy of about 250 kJ without observable rupture of the flexible nets or cables and can be put into service again with some maintenances on the steel vaulted structure. Experimental data such as local strains, peak loads and impact times are recorded by dynamic strain gauges, load cells and a high-speed camera for structural analysis and some complementary suggestions of improving and designing are offered with respect to the joints and components. Finally, the advantages and limitations of the flexible rock-shed are outlined and the limits of the present experimental investigation and the future research for the flexible rock-shed are proposed.

“…Rockfall influence area zonation can help engineers to select effective mitigation measures against rockfall to avoid casualty and property losses [44][45][46]. Perret et al mentioned that according to the total kinetic energy, the rockfall influence area could be classified into the low-intensity zone, medium-intensity zone and high-intensity zone [47].…”

Abstract:In the steep mountainous areas in northwest Xinjiang, where rock mass is broken seriously due to intense freeze thaw weathering, rockfall is one of the most common geological hazards on highway high slopes. Engineering geological investigations on geological hazards along a segment of the G219 highway was conducted, indicating that rockfalls on the high slopes threaten the safety of vehicles on the highway seriously. In this study, a combination of field investigations, laboratory experiments and numerical simulation methods was performed to identify unstable high slopes, simulate the rockfall trajectories and assess the rockfall hazard in the study area. The results show that there are five high slopes (i.e., W01, W02, . . . , W05) where rockfall hazard is extremely serious. Considering both the total kinetic energy and the accumulation rate of blocks, rockfall influence area zonation was performed, leading to the conclusions that the sections of highway on W01 to W05 are located at the medium-intensity low-accumulation zone, high-intensity medium-accumulation zone, high-intensity low-accumulation zone, high-intensity low-accumulation zone and medium-intensity high-accumulation zone, respectively. Based on the analysis, a zonation map was accomplished, which could help engineers select effective mitigation measures against rockfalls to avoid casualty and property losses.
