... ABSTRACT: Active deep-seated gravitational slope deformations (DSGSDs) and interlinked secondary processes such as rockfalls and debris flows pose multiple threats to livelihoods in mountain regions. A currently active part (∼0.35 km 2 ) of the Reissenschuh DSGSD (Schmirn valley, Tyrol...

... concentration and damage in the corner area. The damage degree of the lining structure is classified according to the tensile damage factors, namely, no damage, slight damage, moderate damage, and severe damage. Combining the large deformation of flexible joints can effectively improve the design of tunnel...

... ingress. To resolve the issue, we utilized GPR based Sub-Surface Profiling technology that is capable of capturing fault related deformation features as anomalies. Results of SSP scanning and its interpretation from an underground coal mine in India is presented. Signatures from SSP are found useful...

... ABSTRACT: In Japan, some mountain tunnels are damaged by earthquakes and relative large-scale deformations such as the collapse of permanent lining and the deformation of supports have occurred. Although the earthquake resistant countermeasures for tunnels has been examined recently, some...

... ABSTRACT: Deformation behavior analysis is crucial for ensuring safe operation of the arch dam. This study investigates the deformation distribution and influencing factors of an arch dam in southwest China based on k -means clustering analysis and panel regression models. Results show...

... Movement and Surveying Radar (MSR). The system is deployed at a position whereby it is mechanically steered to conduct sequential interferometric measurements to delineate deformation data from the pit slope. The area that may be scanned is definable, and comprises 186° in azimuth and129° in elevation...

... to the in-situ stress is applied on the inside of the excavation boundary. The pressure is incrementally relaxed until the excavation boundary condition is that of zero normal stress. The extent of plastic yielding (or fracturing) and thereby, the boundary deformation is calculated at each stage of the process...

... ABSTRACT: In the slate belt of Taiwan, there have been numerous studies exploring landslide activity or gravitational slope deformation (GSD) since the 2009 Typhoon Morakot. However, studies evaluating the relationship between present-day activity and long-term deformation have been infrequent...

... ABSTRACT: Anchor cable is widely used in rock slope reinforcement. In the design, the force of the anchor cable is often simplified as a constant load, which cannot reflect the deformation. To accurately evaluate the stability of the slope reinforced with anchor cables under earthquake load...
