Risk Assessment of Geological Hazards in a Tunneling Project Using Harmony Search Algorithm (Case Study: Ardabil-Mianeh Railway Tunnel)
Abstract: During the design
and implementation of underground constructions, the risk assessment and
management of geological hazards are important due to the hazards such as the
water inflow, collision with crushed fault zones, squeezing and instability
around excavation zones. In the present research, it is attempted to study and
assess the risk of geological hazards in 378+021 km of the route of
Ardabil-Mianeh railway tunnel using the harmony search algorithm (HSA). In the
first section of research, after studying structural and geological
characteristics during 24 sections of the excavation route, the risk relating
to geological hazards including the tunnel instability, squeezing, water inflow
and swelling was assessed in three separate classes using HSA. In order to
study the accuracy of results, geological hazards recorded during the
implementation of excavation operations were used. Studies obtained from the
comparison of observed and predicted results indicate the high accuracy of HSA
in the assessment and prediction of geological risks in the tunnelling project.
