RISK ANALYSIS AS A TOOL TO DETERMINE DESIGN LOAD DUE TO EXPLOSION IN A TUNNEL
This paper presents a method for estimation of the design load due to explosion in a tunnel. The method is based on risk analysis together with cost-benefit comparison and was applied in particular for the load bearing structure in Ringen in Stockholm. Risk is defined as a measure of the probability and the severity of an explosion and is expressed in terms of cost. The analysis takes into account risk connected with the accidents or adverse events during the normal operation stage of this tunnel. The stages of the analysis were: to determine causes of an explosion, estimate probabilities, consequences and calculate the risk. Two alternatives of the tunnel were studied: one structure with normal and one with increased resistance. For each alternative, the yearly cost of risk was determined and the savings in risk were compared with the cost for increase of the resistance. (A) For the covering abstract see IRRD E101472.
