SUCCESSIVE CANTILEVERING AND SERVICE GIRDERS

FREIVORBAU UND RUESTTRAEGER

For the last 15 years, the technique of successive cantilevering has been one of the best known methods used in prestressed concrete bridge construction. Basically, two sets of formwork are advanced from one bridge pier towards the middle of the adjoining spans and the bridge is constructed step by step using a cantilevering principle. The bridge piers or the formwork anchored in the ground provide the necessary stability at the construction stage. For this form of construction, service girders are employed, by means of which the shuttering may be advanced independently of the ground location, and the advancing structure and all equipment necessary for the various working stages of construction may be stabilised. The theoretical background to this method of bridge construction is explained; a report is presented on two bridge projects built using these techniques. /TRRL/
