Site Supervisor Interview Question:

Tell me in the design of bridge arguments what considerations should be made to select the orientation of the wing walls?

Submitted by: Muhammad

Some of the most common arrangements of wing walls in cases of bridge arguments are as follows:
☛ Wing walls parallel to abutments: This method is considered to take least amount of time to build and is simple as well. But on the downside this method is not the most economical. The advantage of this type of design being that they cause the least amount of disturbance to the slope embankment.
☛ Wing walls at an angle to abutments: This design method is considered to be the most economical in terms of material cost.
☛ Wing walls perpendicular to abutments: The characteristic of this design is it provides an alignment continuous with the bridge decks lending a support to the parapets.
