Mechanical Characterizations of Joints in Segmented Tunnel Liners Due to Flexural and Thrust Jack Loading (UTI-UTC 43)
This project investigates the mechanical behavior of joints in segmented tunnel liners subjected to flexural and thrust jack loading conditions commonly encountered during tunnel construction and operation. Utilizing both experimental testing and numerical modeling, the research aims to understand the load-deformation response and failure mechanisms at segment joints, particularly under combined loading scenarios. The study is based on data and specimen segments from the Chesapeake Bay Tunnel expansion, with testing conducted to evaluate performance under controlled thrust and bending loads. Analytical models are developed and calibrated to replicate observed behaviors, contributing to more accurate predictions of joint behavior. The outcomes of this project will inform the design and construction of more resilient and efficient segmental tunnel linings, supporting improved safety and performance in underground transportation infrastructure.
