| Abstract: | Based on the construction of an extradosed cable-stayed bridge,this article introduces the principles and objectives of the construction control of the extradosed cable-stayed bridge and the tension method of strand stayed-cable according to its own characteristics.In light with the structure characteristics of the extradosed cable-stayed bridge,it also proposes the principles to control the lower and upper stress of the main beam and the control method that the cable force is strained one time to get the i... |
