Numerical Modeling of Rock Slopes with a Potential of Block-Flexural Toppling Failure
One of the most important instabilities of rock slopes is toppling failure. Among the types of toppling failure, block-flexural failures are more common instability which occurs in nature. In this failure, some rock blocks break because of tensile stresses, and some overturn under their weights, and next to all of them topple together. Physical and theoretical modeling of this failure is studie...
متن کاملFlexural Toppling Failure in Rock Slopes: From Theory to Applications
Toppling failure is one of the most common modes of failure of rock slopes in layered rock strata. Flexural toppling is one of the well-known modes of the failure. This type of failure occurs due to bending stress. In this article, a brief yet comprehensive review of toppling failure is presented. Firstly, the conditions and general mechanism of the failure are described. Then, experimental, th...
متن کاملIdentifying Landforms and Soils by Aerial Photographs
In the process of analyzing aerial photographs to obtain information on the engineering characteristics of soils, the first and perhaps the most important step is to identify the landform. The landform may consist of hills, valleys, plains, terraces, beaches, dunes, and other topo graphic features largely created by the forces of erosion. The im portance of the landform lies in its relation t...
متن کاملFailure and strengthening of granular slopes under horizontal vibration.
We present experimental measurements of a granular slope under horizontal vibration. We use optical particle tracking to measure the motion of surface beads as the slope fails. We find that for all but the largest inclination angles, initial bead motion leads to strengthening rather than an avalanche. The initial motion of the beads is usually intermittent and evolves differently for different ...
متن کاملSlippery slopes of stress: ordered failure events in German banking
Outright bank failures without prior indication of nancial instability are very rare. Supervisory authorities monitor banks constantly. Thus, they usually obtain early warning signals that precede ultimate failure and, in fact, banks can be regarded as troubled to varying degrees before outright closure. But to our knowledge virtually all studies that predict bank failures neglect the ordinal n...
