Webinar on Application of Optical Fiber Sensing Technology in Geotechnical Health Monitoring (Jointly organized by HKIE CVD and PolyU)

Technical Seminar: 

Application of optical fiber sensing technology in geotechnical health monitoring

Date, time & venue

17th February 2022 (Thursday), 17:00-18:00, Seminar via Zoom Meeting

Organized by

HKIE Civil Division and The Hong Kong Polytechnic University

Programme Highlight

The geographical position of Hong Kong makes it susceptible to weather-related threats especially typhoon, like many other tropical and sub-tropical coastal cities. Accompanied strong winds and torrential rains may cause disastrous damages to civil engineering structures as well as the ecosystem. Hong Kong has widely distributed masonry retaining walls (MRW) due to the high demand of developable urban land. Most masonry retaining walls are historical geotechnical structures with high ecological and cultural values. Trees growing on the MRW form an integrated unit with the underneath wall by their roots spreading on wall face and penetrating into slope through joints of masonry blocks. Optic fibre sensing technology has been utilized in this study for monitoring the dynamic behaviour of large trees and stonewall trees under extreme winds. This study also provides a practical method for establishing a smart monitoring and early-warning system for health monitoring of civil engineering structures.

Dr Tao-Yuan TAN

Dr Tao-Yuan TAN is a Research Assistant Professor in the Department of Civil and Environmental Engineering of the Hong Kong Polytechnic University. He obtained his BEng and MEng from the China University of Geosciences and PhD from the Hong Kong Polytechnic University. His research interests include geohazard management, development of optic fibre sensors, and intelligent monitoring of geotechnical structures. He was invited to give presentations in a series of local and international conferences and awarded the 2019 “Ringo Yu” Prize for Best PhD Thesis in Geotechnical Studies by the HKIE. He is the committee member of the Association of Geohazard Professionals (AGHP, U.S.) and a member of IACMAG, ISSMGE, and HKGES. He is currently co-editing one group standard on intelligent monitoring technologies for slopes approved by CSPSTC, China.
