Soil liquefaction describes a phenomenon whereby a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress, usually earthquake shaking or other sudden change in stress condition, causing it to behave like a liquid. The phenomenon is most often observed in saturated, loose (low density or uncompacted), sandy soils. This…
Limit equilibrium methods for slope stability analysis do not, in general, satisfy the overall equilibrium conditions; they must make assumptions regarding the inclination and location of the interslice forces. An alternative slope analysis based on the discrete element method is presented to avoid these drawbacks. A slope in the present model is treated as comprised…
Rockfalls can be a major hazard and a threat to life, properties and infrastructure (highways, railways, bridges, power lines, pipelines, buildings, etc.). Rockfalls are a natural process of cliff and hillside erosion. They consist of large rock fragments from a cliff, or boulders from a slope that bounce, roll, and slide down a hillside and…
General presentation A retaining wall is a structure that retains (holds back) any material (usually earth) and prevents it from sliding or eroding away. It is designed so that to resist the material pressure of the material that it is holding back. from Wikipedia Gravity retaining wall relies on their huge weight to retain the…
