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.

TUNNEL FACE STABILITY ANALYSIS IN SOFT GROUND IN URBAN TUNNELING BY EPB SHIELD (CASE STUDY : 7TH LINE IN TEHRAN METRO) (2011)
<p>Traffic congestion and environmental factors are creating a demand for greater utilization of underground spaces in urban areas. In mechanized excavation of subway tunnels, the Earth Pressure Balanced Shield (EPBS) has been developed in the recent decades ...

3D SIMULATIONS OF A NATM TUNNEL IN STIFF CLAYS WITH SOIL PARAMETERS OPTIMISED USING MONITORING DATA FROM EXPLORATORY ADIT (2010)
The paper demonstrates the application of a hypoplastic model in class A predictions of a NATM tunnel in an urban environment. The tunnel, excavated in a stiff clay, is 14 m wide with 6 m to 21 m of overburden thickness. The constitutive model was calibrated ...

AN IMPROVED ALGORITHM FOR THE METRO-LINE CROSSING MINIMIZATION PROBLEM (2010)
<p>In the metro-line crossing minimization problem, we are given a plane graph G = (V,E) and a set L of simple paths (or lines) that cover G, that is, every edge e ϵ E belongs to at least one path in L. The problem is to draw all paths in L along the edges ...

ANALYSIS OF A BOLT-REINFORCED TUNNEL FACE USING A HOMOGENIZED MODEL (2010)
This communication deals with the effect of tunnel face reinforcement on the wall convergence and on the loads in the lining, studied by means of a homogenized anisotropic model for reinforced ground. While the tunneling process is generally handled in a plane ...

ANALYSIS OF AN UNDERGROUND STRUCTURE SETTLEMENT RISK DUE TO TUNNELINGA CASE STUDY FROM TABRIZ, IRAN (2010)
The tunnel of the Tabriz urban railway line 2 (TURL2), Iran, will pass through an underground commercial center on its way. Too little distance between the tunnel crown and the underground structure foundation will probably cause collapse or excessive settlement ...

BEHAVIOUR OF SEGMENT JOINTS IN IMMERSED TUNNELS UNDER SEISMIC LOADING (2010)
<p>The immersed tunnel technique is a common used technique for river crossings in the Netherlands, but also in the United States and Japan. 80% of the immersed tunnels are built in these 3 countries. The design of the immersed tunnels differs for the different ...
