rockfall protection systems |
| rockfall engineering is the study of rockfall initiation, trajectories and the impact of the solid mass of rock on the infrastructure below, whether protection is present or not. rockfall instability results from |

|
external and internal factors such as temperature variations, scour by wind and water, the action of ice, erosion at the toe of the slope and residual geological stresses within the rock. to counteract the instability, the engineer can choose from a wide range of rockfall protection solutions adopted to suit a particular situation. these solutions can either be passive, hindering or controlling rockfalls and protecting the road and railway infrastructure below the slopes, or active. active systems are those that act on the causes and inhibit its initiation. |

reinforced soil slopes |
reinforced slopes or embankments are typical where the resultant stabilized slope is equal to or less than 70 degrees to the vertical.soft facings characterize slopes. the most widely used soft facing are the wrap around facings where the reinforcement is extended past the front face and lined with a suitable erosion control blanket or geotextile to provide a containment and erosion function. the reinforcement is typically characterized by high strength,low elongation properties. not withstanding the faade chosen,reinforced slopes and embankments have little trouble integrating into the environment and offer significant cost savings over more traditional reinforced concrete structures due to their durability and ease of construction. |
