Safety and Risk of Underground Infrastructures
organised by Prof. E. Alarcon and Dr. I. del Rey
ETSII-UPM, Madrid, Spain
Session Aims and Scope
In the context of this session we will define Risk as an event that if it occurs, it will have a negative (or sometimes positive) and substantial impact on the safety of the users of an underground infrastructure, the inhabitants of the surroundings or the environment.

Risks are normally addressed in two dimensions:

  • Probability of occurrence
  • Consequences when it occurs
To reduce or mitigate a risk, both dimensions must be managed. Ideally, actions focused in the reduction of the probability of occurrence, i.e. prevention, are the most effective measure but, those oriented to the mitigation of the consequences can also be adopted. In all cases, impact on the structures can be reduced, by different means:
  • Designed-in elements that direct, deflect, slow down, resist or contain the matters that cause damage
  • Early preparation to reduce losses, improve the response or speed the recovery.
A third dimension is post-occurrence and is directed to salvage, damage control and recovery.

A complete methodology for risk assessment (overall process of risk analysis and risk evaluation) can be developed by combining different methods for risk analysis, risk evaluation and risk reduction. In all these aspects of risk, computational tools are a key factor for an engineering approach of the analysis of the structural engineering computation as well as in global design an detailing or retrofit of new or existing structures.

Although risk analysis methods were initially developed to assess the safety of potentially dangerous plants and processes in the nuclear, chemical and petrochemical sectors, nowadays, these methodologies are being adopted, incorporated and requested in regulations covering different fields related with underground infrastructures:

  • Road and railway transport
  • Mass transit systems
  • Water management
  • Caverns for hydroelectric plants
  • Routing power or communication galleries
  • Nuclear and chemical hazardous waste deposits
  • Strategic underground facilities (airports, harbors, buildings)
This session focuses on the recent advances on computational tools and methods developed to improve safety and risk management in underground facilities. Some particular topics and applications of this organized session include, but are not limited to: HAZard and OPerability procedures, what-if analysis, Failure Mode and Effects Analysis (FMEA), response surface methods, FOSM methods ,fault and event tree analysis, shock wave overpressure from explosions, BLEVE prevention, radiant flux from pool fires, jet fires, nuclear radiation, seismic actions, geotechnical, uncertainty quantification, floods, reliability and sensitivity analysis, probabilistic and non-probabilistic formulations.

Papers that address either methodological developments or novel applications in topics related to computational methods of structural and mechanical systems are welcome for presentation in this special session.
