A Study on the Improvement of Connection Method for Segment in Tunnel Lining System Using Prestressed Steel Cable by Real-scale Test

Abstract

This paper introduces the improvement of connection method for segment in tunnel lining system using prestressed steel cable and presents the results of real-scale tests. It conducted a study about the applicability and mechanical behaviour analysis of the new method that connects segment tunnel lining using prestressed steel cable by real-scale test. Through the research, it was found that the new method has stronger connection than conventional assembling methods. Also, the new method can be expected to have integrated behavior and stability increase of shield tunnel lining.It is considered that the new method is much more effective than conventional assembling methods.
