Single Tower Cable-stayed Single Cable Plane Design, Construction And Construction Control Technology

Short single tower cable-stayed bridge tower and single cable plane is characterized by low Tower, Liang Gang, cable centralized arrangement; to structural properties, part of the cable-stayed bridge is the bridge between the continuous girder bridge with a bridge between. Cable-stayed bridge is the number of statically indeterminate structure, in the bridge construction process, the cable adjustment and the internal force and internal force distribution of linear bridges will have a significant impact.This paper analyzes the short tower of the single-tower cable-stayed bridge with single cable plane features of the structural system and structural elements, and according to the structure under the effect of the static equilibrium force to classify the different forms were described by the force of their own characteristics. And short single tower cable-stayed bridge tower and single cable plane beam, tower, cable characteristics of the force.Second, single tower cable-stayed bridge on the main beam, the main tower and cable described the common construction methods proposed by secondary stretching tendons for prestressed girder to avoid excessive number of partial rupture and lead to concrete multi-cable time tension tension instead of forming a construction method of the internal forces on the precise control of the main beam construction method, a very good safety and to ensure the construction of the bridge into the force to meet the design requirements of the state.Finally, this cable-stayed bridge construction control theory, method, content and control principles; and the characteristics of cable stayed bridge for the short, Xiaomei Harbour Bridge on the development of a reasonable monitoring program. In the actual construction control, stress, cable tension and elevation for precise measurements and construction features of the establishment under the simulation model to calculate, understand the structure weight, cable tension, load, temperature, factors such as shrinkage and creep deformation and stress under, to provide for the construction and adjustment of cable forces according to the main beam elevation. Construction control while a detailed analysis of the results, and with the construction of the monitoring results were compared with the control, summarizes the calculation of cable-stayed bridge construction control is installed and the changes of various parameters influencing factors, the results can be seen from the bridge construction control line, stress, cable force is to meet the requirements, theory and practice of mutual agreement.This work without back for raising awareness of the structural performance cable stayed bridge, mechanical features, construction methods and Construction Control has a positive meaning, which is to promote the follow-up research work is valuable. In practice, not only can play an important engineering role in guiding practice, you can not back cable stayed bridge on the bridge type of reasonable promotion play a catalytic role.
