GE-001 Tunnel Planning

Tunnel Planning

The Tunnel Planning online PDH course is a part of the Geotechnical Engineering category of courses. This course provides a general overview of the planning process of a road tunnel project including alternative route study, tunnel type and tunneling method study, operation and financial planning, and risk analysis and management.

Road tunnels are feasible alternatives to cross a water body or traverse through physical barriers such as mountains, existing roadways, railroads, or facilities; or to satisfy environmental or ecological requirements. In addition, road tunnels are viable means to minimize potential environmental impact such as traffic congestion, pedestrian movement, air quality, noise pollution, or visual intrusion; to protect areas of special cultural or historical value such as conservation of districts, buildings or private properties; or for other sustainability reasons such as to avoid the impact on natural habit or reduce disturbance to surface land.

The online PDH course is based on Chapter 1 “Planning” of the US Department of Transportation, Federal Highway Administration publication tilted, “Technical Manual for Design and Construction of Road Tunnels – Civil Elements” (FHWA-NHI-10-034). This course is intended to be used by geotechnical, civil and structural engineers and others interested in learning about tunnel planning, design and construction.

Learning Objectives

  • Explain different tunnel shapes and types
  • Define geotechnical investigation required for a tunnel project
  • Discuss waterproofing types for a tunnel project
  • Explain fire and life safety requirements in underground tunnel construction
  • Perform tunnel type study
  • Discuss operational and financial planning aspects of tunnel design
