Programme Highlight

The tragic landslide of a spoil reception site in Shenzhen in late 2015 is a wakeup call not to take these back-of-house facilities for granted.  Hong Kong has three landfills and two fill banks in operation, and it is high time to carry out a health check.


This seminar pools the expertise from both the Mainland and Hong Kong on the management of spoil reception facilities and the associated geohazards.  Ir Peter MOKChief Engineer/Fill Management, CEDD, will talk about “public fill management in Hong Kong”.  He will review the approach to managing the substantial amount of surplus fill generated by the public/private infrastructure projects.  He will go over the issues that Hong Kong cannot avoid to properly manage its fill generation.  The operational safety of the two fill banks receiving over 3,500 truckloads of fill daily will also be discussed.  Dr Anguo Li will first review some of the typical landslides occurred in Shenzhen in the past twenty years, then he will introduce the disastrous landfill landslides occurred in Guangming New District, Shenzhen on December 20, 2015. He will also discuss about the similarities and differences of the landslides in Shenzhen and Hong Kong. Professor Limin ZHANG of HKUST will discuss mass flows in slope failures. He will review several long-distance landslides and present outcome of a preliminary numerical simulation of the mass flow in the tragic landslide in Shenzhen in December 2015.   



Ir Peter MOK is the Chief Engineer/Fill Management of Civil Engineering and Development Department (CEDD), HKSAR Government.   He joined the Government upon graduation from the University of Hong Kong in the 1980s.  He developed his career in the planning and implementation of the developments of Tin Shui Wai, Central Reclamation and Kai Tak, and worked his way up from Assistant Engineer to Chief Engineer.  Now he takes care of the disposal of public fill as well as dredged sediment in Hong Kong.  The operations are not rocket science but require ingenuity to ensure Hong Kong can go on ticking as always. 


Dr Aiguo LI is Vice General Manager and Chief Geotechnical Engineer of Shenzhen Geotechnical Investigation & Surveying Institute. His main research includes slopes, ground improvement and deep excavation etc. He is also a member of International Society for Soil Mechanics and Geotechnical Engineering, Fellow of Guangdong Society for Soil Mechanics and Geotechnical Engineering, Fellow of Shenzhen Geological Association and Fellow of Shenzhen Civil Engineering and Construction. Dr. Li is also a PhD graduate of HKU and his supervisor is Professor C.F. Lee.

Dr Limin ZHANG is Professor of Geotechnical Engineering and Director of Geotechnical Centrifuge Facility at the Hong Kong University of Science and Technology.  His research focuses on slopes and embankment dams, and geotechnical risk assessment. He is Past Chair of Geotechnical Safety Network, Past President of the ASCE Hong Kong Section, Editor-in-Chief of International Journal Georisk, and Associate Editor of Journal of Geotechnical and Geoenvironmental Engineering.
