HOW TO EVALUTE THE SECTION FORCE AT THE TIME OF ASSEMBLING OF THE SEGMENT

Abstract

The segment costs form a large proportion of total tunnel construction, and that cost reduction is becoming a big issue. It is important to estimate the section force for the design which occurs at the stage in the process of assembling the segments correctly, because it account for almost one-half the total section force. In this paper, investigation about the segment behavior at the stage in the process of assembling segments were carried out on the basis of field measurement and numerical analysis were also carried out to establish the analysis model for the design.
