This study investigates the possibility and the propriety of a span divided construction method to the continuous reinforced concrete slab bridges which span a small river.
This method will be used to maintain a water course when a heavy rain visited the area. And also it makes a term of construction works to reduce about 2 weeks than the general existing methods.
There are some bending moment which exceed the design values and some residual bending moment in the 1st construction span. The calculated additional expanses of steel bar is below 5%, and this is less than the purchasing cost of the reducing overflow pipes.
