Rockfall is an extremely rapid process involving long travel distances. Due to these features,
when an event occurs, the ability to take evasive action is practically zero and, thus, the risk …

Rockfall protection embankments are elevated massive structures designed to stop falling
rock blocks. This paper discusses two specific facets of their design: their ability to control a …

ABSTRACT The use of Discrete Element Methods (DEM) to investigate mechanical
properties of geomaterials is growing fast and their applications in geotechnics have …

Flexible, slit, and rigid barriers are common countermeasures to mitigate natural
geophysical mass flows, but presently, quantitative comparisons of their performance are …

The accuracy of rockfall trajectory simulations depends to a large extent on the calculation of
the rebound of falling boulders on different parts of a slope where rockfalls could occur. The …

This paper presents an improved discrete element model, which incorporates stochastically
distorted contact mechanics, for the simulation of double-twisted hexagonal wire meshes …

The accuracy of rockfall trajectory simulations mainly rests on the calculation of the rebound
of fragments following their impact on the slope. This paper is dedicated to the comparative …

Rockfall protection embankments are ground levees designed to stop falling boulders. This
paper investigates the behaviour of geocells to be used as components of these structures …

In a hilly and congested urban environment, use of reinforced concrete barrier for hillslope
protection is common. With some of these barriers, a layer of gabion is placed in front of the …

The normal velocity curve of a falling boulder with time is fitted by a logistic curve. Without
considering the rotational velocity, a logistic equation is used to fit the normal velocity curve …
