  Analysis of Tunnel Rock Cutting by Diamond Wire Saw Blade Using a Finite Element Model

  Different engineering applications including mining, tunnelling, etc. uses mechanical rock cutting process. Rock cutting is the principle work performed for the tunnelling. Various types of rock cutting process are performed these days (i.e., sawing, rotary blade, drilling etc.). Because of urbanization, more and more land is being used for structural development. Thus making underground infrastructure is becoming more important day by day. For underground infrastructure, tunnels plays an important part with subway tunnels, highway tunnels, railway tunnels etc. When constructing any underground infrastructure, vibration is one of the main concerns. It might cause damage to the existing structure around the construction site. As the most commonly used method for excavating the rock mass is drilling and blasting. Thus this method induces vibration that are spread in to the ground. Diamond wire saw have played an important role in recent decades, to perform the cutting process of rock. Diamond wire saw cutting process is widely used for rock excavation because of their high flexibility, high production rate, low noise level, low cost and high energy efficiency, particularly when compared to circular saws.
