Foundations of Bridges and Other Structures 3 foundations supporting simple-and continuous-span bridges can tolerate substantiallylarger deformations than are usually considered acceptable.

DRILLED SHAFTS Although driven piles have long been the deep foundation of choice for bridge design,advances in cast-in-place foundation techno logy, changes in design codes, andconstructability requirements have made drilled shafts a common alternative during thepast 20 years.

Concrete plays an important part in the construction of a suspension bridge. There will be massive foundations, usually embedded in the ground, that support the weight and cable anchorages.

Bridge Types. Bridges are constructed in many different ways and are often identified by. the materials they are constructed from and the method of construction. The. following images can be used to help identify bridges you may see in your. travels.

The span-by-span method is used for multi-span viaducts, where the individual span can be up to 60m. These bridges are usually constructed in-situ with the falsework moved forward span by span, but can be built of precast sections, put together as single spans and dropped into place, span by span.

Reinforced Slab Bridges. For short spans, a solid reinforced concrete slab, generally cast in-situ rather than precast, is the simplest design. It is also cost-effective, since the flat, level soffit means that falsework and formwork are also simple. Reinforcement, too, is uncomplicated.

DRIVEN PILES Driven piles have long been the deep foundation of choice among bridge designers.However, changes in design codes and construction requirements during the last decadehave reduced the dominance of driven-pile foundations for bridges.

Therefore, until tolerabledisplacement limits are increased, the application of spread-footing foundations will likelyremain limited for highway bridges.The changes foreseen for spread-footing design and construction will most commonlyresult from the implementation and evolution of the AASHTO LRFD code.

Arch Bridges. Arch bridges derive their strength from the fact that vertical loads on the arch generate compressive forces in the arch ring, which is constructed of materials well able to withstand these forces.
