Abstract: Malaysia’s first Mass Rapid Transit (MRT) project was officially launched on July 8 2011. The total length of 51km stretches across Klang Valley, 9.5km running underground with 7 stations across the busiest city center of Kuala Lumpur. MRT is expected to be in operation by end of 2016. The project was awarded to MMC Gamuda KVMRT (T) Sdn Bhd. The geological conditions of the Klang Valley makes...
Abstract: Shield tunnelling is one of the most mechanized construction technologies to date. It is governed by its main components, the shield machine, the precast lining segments and the tail gap grouting. Given the low tolerances, the high degree of accuracy and the stepwise repeated construction process, shield tunnelling is hence accessible by methods of mechanical engineering to an extent that is...
Abstract: The Klang Valley Mass Railway Transit in Kuala Lumpur is mid-way through line 2 construction. The line faces several challenges including mixed face conditions, variable ground water and geologic hazards with high potential for large settlements and sink holes. Consequently, the influences on tunnel processes such as advance rates and cutter tool wear are hard to estimate. This paper presents...
