Bridge-In Situ Single Cell Box Girder Deck

In situ casted single cell box girder is fit for span length from 40m to 270m.

The box girders are able to suit for curvy deck and other complex roadway geometry, granting them high aesthetic value.

For bridge span within 70m, constant depth section giving span-to-depth ratio of 20:1 is often used.

For long span bridge, haunched profile is adopted, where the span-to-depth ratio near pier is 16:1, and it changes to 45:1 at the mid-span.

The width of box girder usually varies from 6m to 16m, while the side cantilevers at the top of section are usually of 2m to 3.5m length.
