Evaluation of tunnel safety and cost effectiveness of measures
نویسنده
چکیده
Aim of this paper is to propose a framework for the evaluation of tunnel safety. Two methods for the analysis of tunnel safety, the probabilistic and the deterministic approach, and their characteristics have been described. Probabilistic criteria are proposed for the judgment of personal, societal and economic risks of tunnels. Furthermore some methods to analyse cost effectiveness of (additional) safety measures are discussed. The application of the aspects and methods discussed is illustrated with experiences and results from some practical tunneling projects.

Evaluation of tunnel safety: towards an economic safety optimum
The aim of this paper is to propose a method for the evaluation of tunnel safety using probabilistic risk assessment. The framework includes three criteria; personal-, societal-and economic risk. The use of personal and societal risk is becoming more and more widespread. There are however, still some difficulties in using the economic risk criterion. Thus, as a first step towards economic risk ...
متن کاملEvaluation of structural analysis of tunnel segmental lining using beam-spring method and force-method (Case study: Chamshir water conveyance tunnel)
The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. Therefore, the bending moment act...
متن کاملSelection of Optimum Tunnel Support System Using Aggregated Ranking of SAW, TOPSIS and LA Methods
The selection of optimum support system is a key step in the successful design operation of tunneling, rock mass stabilization and minimization of plastic zone extension around a tunnel. In this context, it is not sufficient to rely only on the experiences of design engineers, but taking all effective measures and parameters is necessary to do a proper choice. In this paper, multi attribute dec...
متن کاملSafety, effectiveness and economic evaluation of intra-operative radiation therapy: a systematic review
Background: Intra-operative radiation therapy (IORT) is the transfer of a single large radiation dose to the tumor bed during surgery with the final goal of improving regional tumor control. This study aimed to investigate the safety, effectiveness and economic evaluation of intra-operative radiation therapy. Methods : The scientific literature was searched in the main biomedical databases ...
متن کاملThe Safety Level of Railway Infrastructure and Its Correlation with the Cost of Preventive and Mitigation Measures
This paper develops a methodology which allows the correlation between the cost which is required for the application of preventive and mitigation measures dealing with accidents which occur within a railway system and the improvement of the level of safety as a result from their implementation. The safety level is expressed either quantitatively, by the decrease of “fatality risk” indicator...
