Vibration Control Seminar 1: TBM Groundborne Noise Prediction Models (Wed, Jan 6, 2010)
Hong Kong Institute of Acoustics
Vibration Control Seminar 1: TBM Groundborne Noise Prediction Models
Speaker: Wilson Ho / Banting Wong, Wilson Acoustics Limited
Venue: N001, Hong Kong Polytechnic University
Time: 6:30-7:30pm, Wednesday, 6 January 2010
In the last decade, many tunnels in Hong Kong were constructed by Tunnel Boring
Machine (TBM). More TBM tunnels are coming in the next decade, including tunnels
for MTR SIL, XRL, KTE and SCL, DSD Lai Chi Kok Tunnel and Tsuen Wan Tunnel,
Central Kowloon Route, etc. For tunnel alignment close to residential buildings, noise
impact from TBM tunnelling may restrict its nighttime operation and may have
implications on the overall construction program. Therefore, extensive noise &
vibration predictions are required during EIA and construction stages. Throughout the
previous TBM projects, groundborne noise prediction models were developed,
improved and becoming more sophisticated. However, the prediction reliability still
has rooms to improve.
Mr. Wilson Ho and Banting Wong have been developing TBM Groundborne noise
models for various TBM projects, including
DSD West Drainage Tunnel, 2009
MTR WIL and XRL Tunnels, 2008-09
CLP Chi Ma Wan and Castle Peak Tunnel, 2003-08
KCRC Lok Ma Chau Tunnel and Kowloon Southern Link, 2003-07
MTRC Quarry Bay Congestion Relief Works, 1998-99
Concept of TBM Groundborne noise prediction models will be presented in the seminar.
The prediction accuracy, pros and cons, practicability and limitations of various models
will be discussed.
