» Construction Condition
  • 1. Construction Environment
    1. Hangzhou bay is wide and is a typical oceanic climate with lots of typhoons, large tidal range and turbulent flow. Thus, the effective working days are less.
    2. nThe soil here is thick and deep, which brings about a series of problems to the design and construction.
    3. The intertidal zone on the south bank is too long and intricate. Thus, normal design scheme and construction scheme will fail to meet the demands.
    4. Environmental erosion here is serious.
    5. It is really dangerous to work in south intertidal zone where it is rich in shallow gas.
  • 2. Construction Difficulties
    1. Large-scale and great work amount. The whole bridge is 36kms long, of which sea part takes up 32kms. The construction of this bridge is huge, which uses 2,450,000 cubic meters of concrete, 820,000ton of various steels, and 5,513 steel casing piles with 3,550 drilled piles, 1,272 cushion caps and 1,428 pier shafts.
