PAS 8810:2016 Tunnel design. Design of concrete segmental tunnel linings. Code of practice

Standard Number
PAS 8810:2016
Title
Tunnel design. Design of concrete segmental tunnel linings. Code of practice
Publication Date
Descriptors
This PAS makes recommendations for the design of concrete segmental tunnel linings. It covers design considerations from project inception through to the end of the service life of the tunnel. As tunnel construction technology is fast changing, some of the recommendations set out in this PAS might not be fully applicable to a newly-introduced technology that does not exist at the time of this PAS publication.
