<p>Tunnels, constructions used to shorten transport routes and to improve road safety, are specific engineering structures where the safe operation is very important. Tunnel Traffic &amp; Operation Simulator (Simulator) was created as a solution of research ...

<p>Based on the international vulgate safety risk managing theory, the Guangzhou Metro Corporation (GMC) summarizes the standard system of safety risk management in metro rail transit project, integrating with criterion files about project on safety risk management ...

<p>Many traffic tunnels in the European Union need records of their conservation and safety status, including fire performance. Besides other countries the German road transport authorities plan to enhance the safety of their tunnels. As an example, the results ...

<p>Estimates of uncertainties and risks of the construction process are<br />essential information for decision-making in infrastructure projects. The construction process is affected by different types of uncertainties. We can distinguish between the common ...

<p>A model for probabilistic assessment of excavation performance of tunnel projects is presented. The model is based on Dynamic Bayesian Networks (DBN) and enables to consider the quality of the design and construction process. It is applied on a case study, ...

<p>A new risk analysis system for estimating the risk factors in tunneling is suggested in consideration of the complex effect in tunnel construction.</p>

<p>Based on CFD method, this paper conducted simulation analysis of lorry and car fires for large cross-section road tunnel. The smoke distribution feature was discussed and the corresponding results of critical ventilation velocity were also compared with ...

<p>These guidelines, prepared by Working Group 2 (Research) of the International Tunnelling Association, are prepared in order to give guidance to all those who have the job of preparing the overall scheme for the identification and management of risks in ...

<p>This paper discusses a consistent procedure to quantify geological, geotechnical and economic risk in tunneling. For an underground excavation a sound rock mass model and a systematic and quantitative rock mass characterization has to be developed. After ...
