conference paper description
Three failures of non-reinforced concrete tunnels in Michigan have been investigated. Descriptions of the failures have been presented, together with geotechnical data for the sites. A probable failure mechanism has been described, as well as design concepts which need to be considered on future projects. Finally, construction procedures to be specified as part of the design process have been evaluated.
