Abstract:The complex and dynamic nature of shield‐driven tunnel excavation, staged construction, segmental lining installation process, and tail‐void grouting necessitate using detailed numerical modeling for predicting ground behavior and response of segmental lining. In this article, results of three‐dimensional advanced finite element modeling are presented for one of the major ongoing construction projects in the North America. Different segment joint models, i.e., rigid joints, perfect hinge joints, Janssen joints… Show more
