Evaluation and Analysis of Passive Defense Structure Requirements in Ahvaz Metro System

With the probability of offensive military threats in Iran, the need for design and construction of structures which can be capable of any threats and the development of safe structures for people living in metropolitan cities in a necessity and inevitable. The design of Ahvaz Metro system with the capabilities of criterion and index has a very high potential for meeting the needs of a large urban safe structure for a large number of people especially those located in the city center. In order to reach this goal, the necessity in the use of the more update research knowledge and with preventive measures, it is possible to reduce or eliminate the enemy’s threats. By implementing the criteria and instructive passive defensive measures in the different stages of design to operation especially in the civil engineering area can be regarded as the most effective step in reaching the standards. But as the first line of Ahvaz metro in under construction, the need for decreasing the threats for the city of Ahvaz located near to borders with neighboring countries is a necessity for structure evaluation and analysis of the entire line in the construction process and prior to the operation level of the project. As there is a lack of efficient criteria or instructions on passive defensive measure for the structures under construction, this research aims to evaluate and analyze the existing design criteria and instruction of passive defensive rules with the design criteria of the Ahvaz Metro for all types of explosives on the structure of the first line in order to reach the possibility of safe point for people using the metro line. The research analysis indicates that the design of the first line does not have the potential for a safe space in the case of danger due to air or ground explosions.
