CEE Research Team to Support First National Observation and Research Station at Mega Bridge

30 Dec 2021

CEE researchers and students setting up sensors and data acquisition units on the HZMB.

A new national field research station for the Hong Kong-Zhuhai-Macau Bridge (HZMB) will be established with the help of a team of researchers from the Department of Civil and Environmental Engineering (CEE). Led by Associate Head Ir Prof. Xia Yong, the CEE Team engaging in this vital national project includes CEE colleagues Prof. Zhu Songye and Dr Dong You and specifically focuses on exploring structural safety monitoring, condition assessment, and maintenance strategies of sea-crossing bridges.

Sea-crossing bridges are always vital to the economic development of highly urbanized coastal areas, yet at the same time they are prone to corrosive marine environment and natural hazards. The CEE team, in collaboration their counterparts of the station, will collect real-time data, assess and predict the in-service condition of the bridge, and develop advanced technologies for intelligent operation and cost-effective maintenance of mega bridges. The structural health monitoring group of CEE has a long historical legacy and reputation in the area, with its research applying to numerous landmark structures like the Tsing Ma Bridge, Canton Tower and Shanghai Tower. The HZMB is the latest example.

National Field Scientific Observation and Research Stations have been set up by the Ministry of Science and Technology (MOST) since the late 1990s. Focusing on ecology, special environments, geophysics and materials corrosion, and now the maritime environment, as well as structural safety, such research stations have been an integral part of the national technology innovation infrastructure. The new HZMB station is one of the three national stations in transportation areas approved by the MOST in October 2021.
