Research on Bearing Capacity Evaluation of a Double-deck Bridge

以某双层桥为工程背景,针对其受力特点,结合成桥后静动载试验,将应变及挠度试验结果与有限元理论值相比较,综合评估其承载能力,并得出该桥在实际荷载作用下的部分受力特性。试验结果表明:桥梁结构的强度和刚度均满足规范要求。以上研究,为分析类似桥型的受力分析及承载能力评估提供一定的工程经验。

This articletakes a double-deck bridge as the engineering background,and based on its stress characteristics,combined with static and dynamic load tests after completion,compares the strain and deflection test results with the theoretical values of finite element analysis,comprehensively evaluates its bearing capacity,and obtains some of the stress characteristics of the bridge under actual loads.The test results show that the strength and stiffness of the bridge structure meet the design requirements.Through the above work,provide certain engineering experience for analyzing the stress analysis and bearing capacity evaluation of similar bridge types.
