摘要:
针对宿州新汴河大桥主桥建立有限元模型进行静载试验的理论计算,根据计算结果确定荷载试验的控制截面和试验工况. 通过现场静载试验,测试了最不利荷载下主梁与主塔的截面应力、主梁挠度、斜拉索索力. 将试验值与理论计算值进行比较分析,应力的校验系数在0.24~0.93之间,挠度校验系数在0.61~0.68之间,索力校验系数在0.25~0.58之间,各项试验指标的试验值均小于理论计算结果. 结果表明:该桥在设计荷载作用下是安全的,具有良好的力学性能.
Abstract:
The finite element model of the main bridge of Xinbian-he river bridge in Suzhou was built for theoretical calculation of static load experiment, based on which the test conditions and control sections were determined. The section stress of the main beam and the main tower, the deflection of the main beam and the cable force increment were tested under the most disadvantage load in the static load experiment. The coefficients of stress calibration, deflection calibration and cable force calibration are 0.24-0.93, 0.61-0.68 and 0.25-0.58 respectively, which are less than the theoretical calculation values. The results show that this bridge is safe with good rigidity and strength under the designed load.
