The article presents a novel yielding mechanism, especially designed for the rock bolt
support. Mechanical rock bolts with an expansion head and equipped with one, two, four …

Housing has some characteristics as an economic good that distinguishes it from the other
goods. Housing can be considered as a commodity and also can be accounted as one the …

The constant growth of cities has led to a shortage of land in metro areas as a result;
numerous transportation issues must be addressed. The design of underground structures …

This paper presents a new testing method for the problems encountered in field testing. To
this end, single-tunnel and twin-tunnel small-scale rock models are prepared in the …

The design of the tunnel demands an adequate analysis to access the possible damage to
the tunnel under different conditions of loading. A huge amount of research studies has …

The objective of the study is to investigate the influence of seismic analysis of tunnel systems
(single and twin tunnels). The seismic analysis is significant for tunnel projects in urban …

According to recent studies and observed failures of underground structures, many
researchers have addressed the design and construction of tunnel lining against …

Generally, during earthquake events, underground structures have experienced a lower rate
of damage than surface structures. Nevertheless, some underground structures registered …

Most of researchers explain that shallow tunnels suffer higher damage compared to deep
structures. Many numerical analyses were carried out in order to verify and compare the …

Blasting operations generate seismic effects in underground mines. These effects apply
additional dynamic loads on the support system, which should bear both static and dynamic …
