Abstract

The chapter delves into the critical aspects of tunnel construction in granitic rock, emphasizing the importance of rock stability during excavation. It discusses the various support systems such as steel ribs, rock bolts, and shotcrete, and how they contribute to the overall stability of the tunnels. The Finite Element Analysis (FEA) conducted using Midas GTS NX software provides valuable insights into the settlement and shear stresses in the tunnels, showcasing the impact of rock quality on tunnel behavior. The case study of the Karwar-Kundapura highway tunnel project in India offers a real-world application of these analytical methods, making the chapter a valuable resource for professionals in the field.
