Artificial Neural Network Model to Predict Surface Settlements Caused by
Abstract: Utilization of TBMs in urban tunnelling is increasing due to the infrastructure requirements of modern-day cities. On the other hand, settlement related risks are still one of the most important considerations which require comprehensive preliminary studies and calculations with very sensitive excavation procedures. In this study, deformation measurements obtained from the deformation stations...

Effects of Cutter Types on Cutter Consumption and TBM Performance in Different and Complex Geological Conditions
Abstract: EPB TBMs are widely utilized for infrastructure and transportation constructions in urban areas as mechanized tunneling is cost effective, safe and rapid when compared to other conventional methods. Today, as a result of technical improvements and increasing demand, design of TBM and cutter head, thus cutter type, cutter size and cutter layout vary in a wide range from manufacturer to...

Investigation of the Vibration Patterns Generated During TBM Excavation
Abstract: TBMs are widely utilized for infrastructure projects and to reach favourable excavation rates, selected TBMs should be operated according to the geological conditions. During excavation, cutters that are in contact with excavation face create vibration patterns which then transmitted to the cutterhead and other parts of the TBM. By recording and monitoring the vibration data and analysing the...

The factors affecting the performance of three different TBMs in a complex geology in Istanbul
Abstract: Four hundred kilometers of metro tunnels are expected to be opened in Istanbul in the near future. The geology of Istanbul is complex changing frequently from very hard rock formation to soft ground in a short length. Mahmutbey-Mecidiyekoy metro tunnels, which are currently excavated by three different EPB-TBMs, gave the unique opportunity to investigate the effect of opening ratio and physical...
