| Extradosed cable-stayed bridge is also known as part of the cable-stayed bridge, whichis as a new type of modern bridge structure developed in recent years, Extradosedcable-stayed bridge has been widely adoption with its superior structural performance andgood economic indicators in the bridge-type bridge design. The prestressed concrete boxgirder is widely used in the main beam design Extradossed Bridge with its wide bending andtorsional stiffness and good stability under partial loads and box girder in good conditionoverall force and so on.In this paper, we will quote the bridge for the study, which is builting in Dongguan City hallwaterways Bridge (Extradosed Prestressed concrete width box girder). Firstly, we will studythe development of low tower cable-stayed bridge and structural characteristics, as well aslow tower cable-stayed bridge the importance of control of the main bridge construction andother issues carried out some research. Followly,we will make a simple discussion to theforce of the wide Box features.This paper will finite the element analysis software Midas/Civil to establish full bridgemodel it wil use unstressed state simulation analysis method in accordance to analyze thesimulation of construction stage of Chudochannel bridge with the construction phase of theconstruction program and calculate the internal forces, deformation and cable tensionsituation of each main beam structure construction conditions. The results show that thecantilever construction method can well ensure reasonable bridge.The impact of construction on the structural parameters controlling the sensitivity analysis,mainly analyzes the structure of the material elastic modulus, material density, constructionloads, prestressed and cable forces and other sensitive parameters, and select some segmentsof the main beam using finite element software Midas/FEA analysis, analysis of a wide boxgirder under different conditions lateral force conditions. |
