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.

DESIGNING SHOTCRETE AS PRIMARY SUPPORT IN TUNNELS (2011)
Since the advent of New Austrian Tunneling Method (NATM), shotcrete as a primary means of support in tunnels has been widely applied. It’s most important features are durability, speed of application and cost effectiveness. This paper introduces some tables ...

GAS GROUND RISKS AND GEOLOGICAL INVESTIGATIONS FOR TBM TUNNELING IN IRAN (2011)
<p>Natural gases are a potential hazard in construction of underground excavations. Encountering with gases usually result in costly delays. Gases occur in a wide variety of geological conditions, so predict the occurrence of potentially hazardous concentrations ...

HIMALAYAN GROUND CONDITIONS CHALLENGE INNOVATION FOR SUCCESSFUL TBM TUNNELLING (2011)
From the tunnelling perspective, the Himalayas arguably pose the most challenging ground conditions almost anywhere in the world. One of the prime reasons for this is that they are the youngest of the mountain chains. They are demonstrably rising faster than ...

NEW TECHNOLOGIES FOR SHALLOW TO DEEP UNDERGROUND CONSTRUCTION IN URBAN AREA (2011)
<p>The utilization of underground space becomes a more important issue in megacities of the world in order to build more functional and advanced cities. However, because a lot of underground structures such as lifelines have already been developed in the megacities, ...

NONLINEAR EARTHQUAKE BEHAVIOUR OF HIGHWAY TUNNELS (2011)
This paper describes the Arhavi Highway Tunnel which has two tubes, its geometrical properties, finite element model, and the nonlinear earthquake behaviour under a huge ground motion considering soil-structure interaction. The Arhavi Highway Tunnel is one ...

NUMERICAL ANALYSIS OF TWIN ROAD TUNNELS USING TWO- AND THREEDIMENSIONAL MODELLING TECHNIQUES (2011)
<p>The design of near-surface civil infrastructure requires detailed consideration of the geological/ geotechnical conditions, excavation geometry and sequence, and ground support measures to ensure stability of the underground openings and minimal impact ...

PROBABILISTIC RISK ASSESSMENT OF EXCAVATION PERFORMANCE IN TUNNEL PROJECTS USING BAYESIAN NETWORKS: A CASE STUDY (2011)
<p>A model for probabilistic assessment of excavation performance of tunnel projects is presented. The model is based on Dynamic Bayesian Networks (DBN) and enables to consider the quality of the design and construction process. It is applied on a case study, ...

QUALITY AND RISK MANAGEMENT CONSIDERATIONS FOR VERY SHALLOW SOFT GROUND CONVENTIONAL TUNNELLING IN URBAN SETTINGS (2011)
<p>The construction of shallow mined tunnels in urban settings is frequently undertaken by use of conventional tunneling methods. In soft ground under shallow cover the construction techniques rely largely on the use of pre-support measures and ground improvement ...

THE IMPACT OF EARTHQUAKES ON TUNNELS IN DIFFERENT ROCK MASS QUALITY Q (2011)
The impact of earthquakes, due to ground shaking, which affects the whole tunnel length from ovaling of the tunnel cross section, is investigated in this thesis. The influence of rock mass quality Q and the tunnel dimension is also studied. Finally, an approach ...

THE STABILITY OF THE EXCAVATION FACE OF SHALLOW CIVIL AND MINING TUNNELS (2011)
The stability of the excavation face of shallow tunnels excavated in difficult ground conditions is currently a relevant problem in the sector for tunnelling and mining. Even though face-reinforcement interventions with fibreglass dowels have proved to be ...
