【摘要】 以现代预应力混凝土连续梁设计理论、有限元法、随机振动、振动测试与分析技术为理论基础,对灵石县工农桥的荷载试验方法进行研究设计。实测结果与理论计算的结果对比表明:桥梁结构主要构件混凝土强度满足设计要求,整体刚度较好,整体工作性能被评为"较好"状态。桥梁上部结构整体工作性能符合设计要求及相关规范要求。更多还原

【Abstract】 This paper presents a study of load test of the Lingshi bridge,combined with modern prestressed concrete continuous beam design theory,finite element method,random vibration,vibration testing and analysis technology.The comparison between the measurements and calculated results indicate that the main component of bridge structure concrete strength to meet the design requirements;the overall rigidity and overall job performance could be rated as good state.The overall performance of bridge upper structure also meets the design requirements and related standards.更多还原
