Evaluation of Harmful effects of Dynamic Loads on 4th Line of Tehran Metro Support System Caused by Earthquake

The risk of earthquakes is one of the main concerns of human societies, particularly for infrastructure in Iran country and the metropolis of Tehran. Considering heterogeneous geological conditions and the presence of multiple faults, Tehran, would be prone to dangerous earthquakes. Due to the high capacity Tehran metro transport system and mass of the population that uses this system, it is necessary to conduct a detailed analysis of seismic performance of the structure of the tunnel support system. Experience shows that the application of finite element analysis achieves relatively accurate and convenient results. In this regard Darvazeh-Dowlat station as one of the busiest subway stations has considerable importance. Seismic analysis performed and the results obtained shows that Tehran metro support system will have proper performance and will have enough safety factors against an earthquake but the soil structure on the top of the tunnel and ground structures will face some destructions.
