摘要
为有效地控制大跨径斜拉桥主桥线形,该文采用MIDAS/Civil建立有限模型,对斜拉桥主桥支架系统受力、稳定性和变形进行分析,结果表明,该支架系统安全可靠,成功地控制了主桥边跨桥梁变形。
In order to effectively control linear of long-span cable-stayed bridges,this paper established finite element model using MIDAS/Civil analysed stresses,stability and deformation of cable-stayed bridge main bridge. Results shown that the supporting system was safe and deformation of side span box girder was controlled well.
