<p>Within the project entitled &ldquo;Models of formation and spread of fire to increase safety of road tunnels&rdquo;, it was necessary to devise a method how to record airflow velocity during the fire in situ tests in road tunnels. Project is in first year ...

<p>In this research, the prospect of tunneling by cut and cover and New Austrian Tunneling Method (NATM) for underground metro rail system in Dhaka city was evaluated. Both conventional analysis and 2D finite element analysis using an elasto-plastic constitutive ...

<p>An optimization model was developed to obtain the ideal values of the primary support parameters of tunnels, which are wide-ranging in high-speed railway design codes when the surrounding rocks are at the III, IV, and V levels. First, several sets of experiments ...

<p>Design of an appropriate ventilation system is one of the main concerns in the construction of subways. In this paper, thermal comforts of side-platform stations are investigated by numerical methods. For the numerical simulation, grids are generated by ...

<p>This paper shows the results of the analysis of the data acquired during the excavation of the new &ldquo;Fabriano&rdquo; Tunnel along the railway line from Rome to Ancona in Italy. The comparison between the results of the analyses and the consolidation ...

<p>This paper reports the ground improvement and excavation of a cross passage between two shield tunnels for the construction of Tu-chen Line of Taipei Rapid Transit Systems. Jet grouting was conducted for soils around the cross passage before the tunneling ...

<p>Generally, two-pass lining systems are used for transportation tunnels constructed using the New Austrian Tunneling Method (NATM). The initial lining can support a significant portion of the long-term ground loads and thus reduce the design loads on the ...

<p>World wide, we see developing nations build new infrastructure as well as developed citeis rehabilitating and expanding their infrastructure to meet the demands of increased population, energy efficiency, and environmental awareness of the public. Working ...

<p>A Dynamic Bayesian Network (DBN) model for probabilistic assessment of tunnel construction performance is introduced. It facilitates the quantification of uncertainties in the construction process and of the risk from extraordinary events that cause severe ...

As every construction project is quite different according to the type of construction, 3D-representations on design, estimation, construction, and management also need to be different. While the 3D-approach has been widely applied to building projects, it ...
