Download presentation: Assessing #Tunnelling Induced Impact to Mitigate Damage

At the MetroRail Asia 2011 conference held in New Delhi, India, Dr Nagen Loganathan from Parsons Brinckerhoff shared on ‘Assessing Tunnelling-Induced Impact to Mitigate Damage on Adjacent Structures’.

In his presentation, he mentioned the basics of Ground Loss, Face Loss, Shield Loss, and Tail Loss, and how it can possibly cause tunnelling-induced ground movements. Towards the end of the presentations, he also did a case study on the North-East line in Singapore.

DR NAGEN LOGANATHAN (LOGAN)

Logan works for Parsons Brinckerhoff in Sydney, Australia, as a Technical Executive for tunnels. He has more than 25years of working experience in underground construction and design in Australia, Singapore, Malaysia, Hong Kong, Indonesia, Thailand and Sri Lanka. This includes tunnel alignment and geotechnical risk; third party property and services impact assessment along the alignment; and groundwater study, vibration and noise assessment and constructability. Detailed study for projects has included tunnel boring machine bored, New Austrian Tunnelling Method, instrumentation monitoring and interpretations, deep excavations, and retention systems design for cut-and-cover tunnels.

His experience in geotechnical engineering includes preparing geotechnical baseline reports that outline the geotechnical risk baseline along the alignment; design of road embankments, including settlement study, road cut slope stability and landslides; shallow and deep foundations; and ground improvement methods. Logan has published more than 25 technical and research papers in local and international journals and conferences, including a recent monograph ‘An Innovative Method for Assessing Tunnelling-induced Risk to Adjacent Structures’.
