| 摘要： | Chris Pope, project manager for National Highways, describes the location of the Severn Bridge as a 'horrible environment for steel' -unfortunately it is the material used both for the bridge deck itself and the cables. The 1.6km Severn Bridge is one of four structures taking what is now the M48 across the Severn estuary. The central span is nearly 1 km. The structure is one of the UK's only parallel strand bridges, with the 511 mm diameter main cables made up of 8,322 parallel 5mm wires. Mr Pope says: 'Most of the bridge is fine, because we have well-established paint systems that protect the steel.' However, this does not apply to the cables. |
