Cut and Cover Tunnels Timed & Monitored

The Cut and Cover Tunnels Timed and Monitored online PDH course is a part of the Geotechnical Engineering category of courses. This course is Timed & Monitored (T&M) to satisfy the requirements of the state of Ohio.

This course provides guidance on the construction methodology and excavation support systems for cut-and-cover road tunnels, describes the structural design in accordance with the AASHTO LRFD Bridge Design Specifications, and discusses various other design issues.

The intent of this course is to provide guidance in the interpretation of the AASHTO LRFD Specifications in order to have a more uniform application of the code and to provide guidance in the design of items not specifically addressed in AASHTO (2008). The designers must follow the latest LRFD Specifications. A design example illustrating the concepts presented in this course is presented as an Appendix for informational purpose. Other considerations dealing with support of excavation, maintenance of traffic and utilities, and control of groundwater and how they affect the structural design are also discussed.

The online PDH course is based on Chapter 5 “Cut and Cover Tunnels ” 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

At the end of the course, you will be able to:

  • Describe the construction methodology of cut and cover tunnels
  • Discuss excavation support methods
  • Explain structural systems used in cut and cover tunnels
  • Define loads acting on the tunnel
  • Explain structural design methodology for the design of the tunnel
  • Discuss groundwater control methods
