| dc.description | In recent years, tunnelling industry showed high demand on Steel Fibre Reinforced Concrete (SFRC) precast segment, especially in major tunnelling works in the world. During the construction of tunnel, damage or defects is unavoidable, which has become one of the major quality issues throughout the tunnelling projects. Lots of study focused on the structural behaviour of the tunnel itself, but lack of solution on method to prevent the occurrences of defects during tunnelling works. The study aims to examine the factors that promote the occurrence of defects through a quantitative survey on both frontline worker and management level, in order to understand and eventually formulate a new method or procedure to minimize the defects on the precast segment. At the same time, the study objective is to develop a tunnel defect framework to explain the influences of factors towards the tunnelling defects. The data collected ranged from inspection record, visual inspection, and questionnaire survey. The main input in the tunnel defect framework was from the data collection which consist the type of defects, root cause of defects and preventive action to minimize the defects. From this information the framework was design and with the help of the tunnel contractor, the framework was implemented in the revised method statement for tunnelling works. This revised method statement was used by the contractor during the construction of Section 2 tunnel from KL Sentral Station to Pasar Seni Station. After the completion of section 2 tunnel, the total number of defects from Section 1 tunnel and Section 2 tunnel was compared and the result show that the numbers of defects have reduced by 75%. The preventive action in the revised method statement was implemented during manufacturing phase, delivery phase, project site handling phase and tunnel lining erection phase. From this research, the future tunnelling works may use this tunnel defect framework in minimizing the occurrences of the typical defects in tunnelling works.,Master of Science,Certification of Master's / Doctoral Thesis" is not available" | - |
