Lawrence Lee, Senior Construction Engineer - Civil, MTR Corporation

Dr. LEE is a chartered civil and geotechnical engineer and has over 20 years of experience in underground construction in Hong Kong at urban areas on both Tunnel Boring Machine and Drill and Blast tunnels worked as client, consultant and contractor firms. He is now currently working as Senior Construction Engineer in MTR Corporation Limited and responsible for new railway extension on Admiralty South Overrun tunnel of Shatin Central Line with Drill and Blast method at highly population density area. He also worked two drill and blast tunnel projects in South Island Line, Lai Tung Tunnel at Ap Lai Chau and Nam Fung Tunnel at Wong Chuk Hang in the past years in MTR Corporation. 

Recently, Dr. LEE participates on resolving engineering problems using an intelligent model. In the recent doctorate research, with the use of Artificial Neural Network and Genetic Algorithm, optimise the important blast parameters such as Powder Factor and Pull Length and improve the productivity on blasting industry at urban area with the limitation of blast-induced vibration from the blast records of MTR South Island Line project.

Appearances:



Seminar Day One @ 13:00

Development of an Artificial Neural Network for Optimization of Tunnel Blasting Design

Artificial Neural Network (ANN) model is widely used over the world for analyzing and optimizing difference engineering problems. In this research, the author use multi-layers perception (MLP) to analyze and predict the tunnel blast vibration on making use of the past blasting records.
