Effects of EPB Shield Tunnelling on Ground Surface Settlements: A Case Study in Kenny Hill Formation
Abstract: The first Malaysia metro line, the 51km-long Klang Valley MRT Sungai Buloh – Kajang (SBK) Line, features a 9.5km underground section within the densely populated urban area of Kuala Lumpur city. The geological conditions through which the underground section was constructed can be distinctly demarcated as two main formations namely Kuala Lumpur Limestone and Kenny Hill Formation, of which...

Finite Element Evaluation of Tunnel-Piled Structure Interaction in Complex Ground Conditions
Abstract: Underground tunnelling works in densely populated urban environment can give rise to deformation of the surrounding ground. The ground deformations can cause potential damage to the adjacent structure foundation and lead to untoward structural distresses. In one of the locations of the recent tunnel construction for MRT development in Kuala Lumpur, Malaysia, the tunnel is expected to be...

This paper attempts to explore if the decision-making criteria adhered to “iron triangle law” at the early project appraisal stage, and also the related “cost-benefit analysis”. Often, the “iron triangle” criteria is hardly applied by decision-makers in this...
