Understanding cross passage ground-structure interaction using data from the Seattle Northgate Link transit extension project (UTI-UTC 39)
This research project investigates the complex ground-structure interaction that occurs during the construction of cross passages in soft ground tunneling environments. Utilizing detailed instrumentation and monitoring data from the Seattle Northgate Link Transit Extension Project, the study aims to quantify the effects of cross passage excavation on segmental tunnel linings and the surrounding ground. It focuses on assessing deformation patterns, ground movement, and changes in internal tunnel forces induced by cross passage construction activities. The project employs numerical modeling and empirical analysis to validate field observations, offering insights into stress redistribution and liner performance. By improving the understanding of these interactions, the research supports the development of safer and more efficient design guidelines for cross passages, particularly in challenging geotechnical conditions common in urban tunneling projects.
