Tunneling is a specialized field within civil engineering that involves the construction of tunnels for various purposes, such as transportation, utilities, and mining. This process requires careful planning and execution to ensure safety and efficiency, often utilizing advanced techniques and machinery to excavate and support the tunnel structure. The design and construction of tunnels can vary significantly based on factors like geology, tunnel size, and intended use. Engineers must consider aspects such as groundwater management, ventilation, and structural integrity to create safe and functional underground passages that meet the needs of modern infrastructure.
