Project description

The Hong Kong – Zhuhai – Macau Bridge (HZMB) Fixed Link project provides for a fixed link between the two Chinese economic centres Hong Kong and Macau (both of which are Special Administrative Regions within PR China) and the mainland of China at Zhuhai. The whole link, which measures some 50 km in length, has been divided into several major sections. The Main Bridge section of the HZMB runs from the (marine) borderline of Hong Kong to the Border Crossing Facility (BCF) Island for the coast of Macau / Zhuhai. The Main Bridge section has a length of approximately 30 km and includes a 6 km immersed tunnel that is flanked by 2 artificial islands to accommodate the transition to the bridge part that run towards Hong Kong and Macau / Zhuhai. The bridge part of the Main Bridge section includes various box-girder and cable-stayed bridges. The Link will carry a three-lane dual carriageway with a design speed of 100 km/h and is designed for a 120 year design life. To accommodate the passing of 300,000 tonnes vessels, the tunnel will be approximately 40 m below the seabed.

Scope of work

Some of the key issues of the HZMB Main Bridge tunnel and island include:

  • Studies to structural and foundation concepts (settlement behaviour) for the immersed tunnel and in-situ tunnel on newly reclaimed artificial islands in poor soil conditions, including relevant interfaces;
  • Offshore transport & Immersion of tunnel elements
  • Design for Earthquakes
  • Island shape and revetment design
  • Tunnel Safety and Ventilation Concept
  • Durability
  • Management of Quality & Risk
  • Deformation & Settlement
  • Environmental protection including protection of the White dolphins
