Abstract: This paper presents an implementation of Bayesian network (BN) and structure learning algorithm to explore the interactions and causal relationships among excavation features of an earth pressure balance tunnel boring machine (EPBM). This study was performed on a data set from the State Route 99 (SR99) tunnel construction in Seattle, WA. A score-based structure learning algorithm was used to...
Abstract: 1.1Problem This paper discusses the monitoring of National Grid Power Tunnel’s new segmental concrete tun-nel linings using embedded distributed optical fibre strain sensing. Fibre optic cables were installed within 36 segments during manufacture in order to monitor strain following installation of the segments into the ground. The objective of this paper is to discuss how embedded fibre optic...
