HZMB

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:

  • Review of Preliminary, Final design to confirm before entering the tender and procurement stage. In this stage TEC prepared the technical specifications and assisted the Client in the compilation of the tender documentation for the first large D&B contract in China.
  • Review of Detailed Design and Consultancy during Construction phase. TEC is supposed to bring in the specialist expertise regarding interaction between immersed tunnel design and construction and knowledge about critical details (ongoing).
  • CPT-U special study to introduce in China the use of cone penetration tests as an economic way to explore ground conditions (study was performed for HZMB project).
  • (Detailed) parallel analyses (special studies) to confirm the detailed design on critical issues, such as the longitudinal design including joint design, seismic analyses and cross section structural analyses.
