| Abstract | Conventional tunnelling in Thailand has been developed for a long time ago since 1907, the first railway tunnel in Thailand “Khun Tan Tunnel” was constructed. The lessons learned summary of tunnelling projects is important and useful to delivery the experience. This thesis has studied the lessons learned from conventional tunnelling for railway tunnel construction. The tunnel was excavated through the carbonate rock of the Saraburi Group. The objectives are considered in four main topics, the geological condition, the support design, the instability problem and the construction time. The data was collected from the contractors and consultants of the tunnelling project. In conclusion, the weathering of limestone in this project does not affect the tunnel stability. Although the limestone is weathered, the mass of rock is still hard and massive. There are three tunnel behaviours occurred, block fall, roof collapse, and cave-in. The understanding of tunnel stability is vital for contractors and supervisors to avoid instability due to improper construction sequences. The advance rate of this project is lower than the other projects and the norm in tunnelling. The timeconsuming in each tunnelling activity ( drilling time, charging time, ventilation time, loading and scaling, and supporting time) takes a long time than the norm in tunnelling. |
