| Abstract: | This paper presents the effect of Segment thickness during Shield TBM tunnelling in case study. In order to perform this study, the ground condition developed in the investigation site are reviewed and analysed. It is also carried out the construction problems occurred in the site during Shield TBM tunnelling. Several Segments were broken partially during advance tunnel by jacking pressure. The data surveyed from site are analysed in order to investigate the cause of Segment break. The numerical and analytical evaluations are carried out to examine the effect of Segment behaviour. From the results, it is found that the main causes of Segment break may be the jacking system and Segment thickness. In addition, new jacking technique is suggested to install safely the Segment during advance tunnel by jacking. |
