... are to define the possible deformation that the blasting process could engender to the benches and its effect on bench’s stability as an individual case and on the overall stability of the slope in general. Introduction Drilling and blasting is a preferred method of rock excavation world-wide due to low...

... Abstract Time-dependent rock deformation is considered to precede dynamic failure in many rock-engineering projects and natural geohazards. In order to understand long-term performance of brittle rocks, we gather mechanical load, strain, acoustic emission (AE) and digital image correlation...

... an attempt was made to compare how some aspects of Biot coefficient determination influence its values. The tests were performed on a triaxial test system PIK-UIDK/PL where deformations are measured by LVDT sensors. The Biot coefficient was calculated using two different equations. The results from three...

... more broadly investigated in our earlier work. Beside occasional rockfalls which are routinely detected by annual TLS monitoring, it was possible to track the pre-failure deformations preceding a series of rockfalls, reaching 0.3 m 3 in volume with 0.5 annual reoccurrence probability. Monitoring...

..., characterized by large, time-dependent and anisotropic deformation. Recently, a new survey gallery (SMP4) began to be excavated along the axis of the future base tunnel at a depth of about 600 m. Squeezing conditions have been met again when SMP4 crossed the same Carboniferous formation. Practical problems have...

... Abstract Tunnels are complex constructions, generally built in difficult geological contexts. When dealing with underground structures, the study of ground deformations is a key aspect to consider in order to guarantee safety during the tunnel excavation and construction quality. One...

... to be considered for support design [2]. Rock support in burst-prone ground needs to resist large deformations due to rock "dilation", called bulking, during the violent failure of rock [1]. The term "bulking" is used to describe volume increases of the rockmass near an excavation due to geometric non-fit...

... Abstract Tracking of surface deformations is typically achieved using periodic measurements of both vertical and horizontal deformations using conventional, Ground Positioning Satellite (GPS), and or photographic techniques. Within the last decade, satellite based methods have also found...

... (InSAR) based on satellite images is used. This technique is sensitive to very small ground deformations and allows early detection of movements. Introduction Landslides are one of the most expensive hazards considering their impact on infrastructures and their direct and indirect cost. In situ...

... Abstract Rock stress is causing unwanted deformations of deep underground spaces. Large deformations increase the risk of failure. The underground excavation causes rock stress changes in the surrounding rock mass, and the resulting deformations can be measured. In this paper, we present...

... Abstract Climatic actions are one of the factors controlling the evolution of slopes, this paper is devoted to a specific effect, relatively little studied, related to the effect of climate-driven temperature changes on rock massif deformation. The particularity of the study is to focus...

... and supports were completed, inner lining concrete was started. However, sudden deformations occurred between Km: 341 + 040 − 341 + 114, and a sudden failure occurred in this part of the tunnel (figure 3). After this stage, the tunnel works had to be suspended. The main purpose of the present study...

.... A satisfactory estimate of the reservoir load, thermal and irreversible drift components has been obtained for most of the instruments. As expected, the influence of temperature is lower for the instruments deeply embedded in the rock mass. The deformations recorded on the left and right bank of the dam have...

... Abstract The Alhama de Murcia Fault (AMF) is an active fault located in the SE of Spain. This fault developed a ~80 m thick band of highly deformed clay rich gouge with a marked tectonic fabric (foliated gouge) that constitute a notable anisotropy. In this work we present the result...
