Tunnel Engineering
The design and construction of tunnels i.e. tunnel engineering is among the most specialized fields in geotechnical engineering and myriad issues must be addressed before a tunnel can become operational.Tunnels are important underground structures that accommodate movement of people, vehicles, water, materials etc.  In this section tunnel engineering aspects such as: tunnel design, tunnel construction, microtunneling, tunnel monitoring, tunnel rehabilitation and risk assessment are included together with other important publications related to tunnel engineering.

SEISMIC RESPONSE OF CIRCULAR TUNNELS: NUMERICAL VALIDATION OF CLOSED FORM SOLUTIONS (2012)
This paper presents a parametric investigation of the seismic response of circular tunnel. The dynamic response in non-linear conditions due to seismic shaking is analysed numerically making use of the finite element program ICFEP in non-linear conditions. ...

DESIGN AND CONSTRUCTION OF TUNNELS UNDER SEVERE SEISMIC CONDITIONS. THE CASE OF KADIKOY-KARTAL METRO LINE IN ISTANBUL (2011)
<p>This article describes briefly the main assessments on the approaches used by engineers in quantifying the seismic effect on an underground structure, both referring to deterministic either probabilistic methods. However, the main purpose is that of proposing ...

A CASE RECORD OF BORED TUNNELS IN SAND BASED ON THE KAOHSIUNG MASS RAPID TRANSIT SYSTEM PROJECT (2011)
<p>A case study associated with shield-machine bored tunnels in sand is presented in this paper. Observations show that driving the first bored tunnel resulted in up to 10 mm of surface settlement, and the ground between two tunnels seems to have been affected ...

AGAINST LIMIT STATE DESIGN IN ROCK (2011)
It is inappropriate, if not meaningless, to attempt to apply limit state design methods, such as those encapsulated in Eurocode 7, to the design of primary support for tunnels in rock, particularly weak rock or any rock under high stress. By reference to some ...

ANALYSIS OF SHOTCRETE LINING OF UNDERGROUND TUNNELS (2011)
<p>Shotcrete is a process where concrete is projected or &ldquo;shot&rdquo; under pressure, using a feeder or a &ldquo;gun&rdquo; onto a surface to form structural shapes including walls, floors, and roofs. The surface can be wood, steel, polystyrene, or any ...
