A posteriori studies of rock slope instabilities generally show that rockfalls do not occur at random locations: the failure zone can be classified as sensitive from geomorphological evidence. Zones susceptible to failure can therefore be detected. Effects ...

The Swiss Alptransit System (also called NEAT) is an important element of the new European high speed railway network . This system, which is currently under construction, consists of two railway axes - the Gotthard and Lštschberg Axes - which will pass through ...

<p>In weak or faulted rock and high overburden considerable displacements occur during excavation of tunnels and galleries. In most cases the behaviour of the ground is not ductile, but governed by different failure modes. In the design stage it is important ...
