Evaluation of the NATM tunnel load on concrete lining using the ground lining interaction model

KSCE Journal of Civil Engineering, 2014
This study presents a Ground Lining Interaction (GLI) model to consider the deterioration of primary supports and realistic ground conditions in evaluations of accurate New Austrian Tunnel Method (NATM) tunnel loads acting on concrete linings.

Optimization of jet‐grouted support in NATM tunnelling

International Journal for Numerical and Analytical Methods in Geomechanics, 2004
AbstractAccording to its designation, horizontal jet grouting (HJG) is performed horizontally at the tunnel face in order to form a support structure of improved soil. HJG is employed to reduce the surface settlements in urban tunnelling when buildings and other infrastructure sensitive to settlements are encountered.

Role of engineering geology in NATM construction

Geological Society, London, Engineering Geology Special Publications, 1995
Abstract The basic design philosophy of the New Austrian Tunnelling Method (NATM) of construction is implicitly reactive; it has been referred to as an observational method as monitoring is required to allow the optimization of support and to ensure that deformations are maintained within the definitions of safety.

Application of Jet Grouting in NATM Tunneling

2001
ABSTRACT Even though jet grouting has been successfully applied in ground improvement over the last 20 years, little is known about the mechanical properties of the improved soil obtained from this method, referred to as soilcrete. In this paper, first steps towards chemomechanical modeling of soilcrete by means of nonlinear finite element (FE ...
