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 ...
<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 ...

The paper presents comparison of 2D and 3D analyses of an exploratory adit of a NATM tunnel in stiff clays using two constitutive models (hypoplastic model for clays and Mohr-Coulomb model). The stress-release factor β of 2D simulation has been optimised to ...
