Research On Construction Control Of Sanwei Road Cable Stayed Bridge

According to the Sanwei Road cable-stayed bridge which interchanges across the Luanhe river in Chengde riverfront district,a finite element model is established. Then the structural analysis of entire bridge in construction control scheme, design and practice is carried out.The definition, development and application of the cable-stayed bridge is introduced firstly.Then this paper briefly introduces the stress characteristics of cable-stayed bridge,and emphasizes the importance of monitoring the construction of cable-stayed bridge during construction.The second and the third parts introduce the basic theory of construction control and the specific engineering background and main design points of each part of the structure.The fourth part of the paper elaborates on establishing the Sanwei road cable stayed bridge model which is based on full bridge space beam element. From the preintegration of various materials to the specific details of the modeling process, and then to the simulation of construction process, this paper introduces all these in detail.Simulating the project correctly and comprehensively palys a crucial role in the construction control of the projectFinally, based on the situation of Sanwei road cable-stayed bridge, this paper presents the control target and contents of the bridge. The paper introduces the monitoring methods and theoretical basis in detail of each monitored object. By using various advanced monitoring technology, it makes the monitoring work more smooth and accurate, guarantees the safety and good quality of Sanwei road cable-stayed bridge.
