INVESTIGATING THE EFFECT OF TUNNELLING ON EXISTING TUNNELS (2015)
Standing J.R.
,
Potts D. M.
et al.
<p>A major research project investigating the effect of tunnelling on existing tunnels has been completed at Imperial College London. This subject is always of great concern during the planning and execution of underground tunnelling works in the urban environment. ...

IMPACT OF OVERHEAD EXCAVATION ON AN EXISTING SHIELD TUNNEL: FIELD MONITORING AND A FULL 3D FINITE ELEMENT ANALYSIS (2013)
Wang F.
,
Zhang D. M.
et al.
<p>This paper studies the impact of overhead excavation on an existing tunnel through both field monitoring and a full 3D numerical model. It is found that the excavation induced longitudinal heave of the tunnel is uneven with maximum heave occurring below ...

3D SIMULATIONS OF A NATM TUNNEL IN STIFF CLAYS WITH SOIL PARAMETERS OPTIMISED USING MONITORING DATA FROM EXPLORATORY ADIT (2010)
Svoboda T.
,
Masin D.
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)
Nöllenburg M.
<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 ...

ESTIMATION OF TIME DEPENDENT GROUND PARAMETERS IN TUNNELLING USING BACK ANALYSES OF CONVERGENCE DATA (2009)
Fortsakis P.
,
Kavvadas M.
The paper uses the strongly time dependent convergence measurements from a tunnel excavated in heavily sheared flysch to estimate the creep-related rockmass parameters by 2D numerical analyses using the ABAQUS finite element code. Various techniques are evaluated ...
