摘要
对某下承式混凝土刚性系杆拱桥进行了荷载试验及数据分析,采用大型有限元程序Midas建立空间梁格模型,并进行了仿真分析;对多种试验工况下桥梁变形和截面应力的实测值与理论值进行了比较;结果表明:桥梁变形和截面应力的实测值与理论值吻合较好,桥梁的结构强度和刚度达到设计要求。
The paper undertakes the load tests and data analysis of some through supported concrete rigid arch bridge, adopts the large-scale finite element program, Midas, to establish the space beam grid, undertakes the simulated analysis, compares the tested and theoretic values for the bridge deformation and section stressed in various test conditions, and proves by the result that the tested value can better consistent with the theoretic value of the bridge deformation and the section stresses, and the structural strength and stiffness of the bridge meets the design demands.
