以某桥为例,对该桥中某桥墩进行现场试验检测,结合该墩的施工流程与当地的环境条件,对该墩的裂缝分布及成因进行详细的分析,并通过理论计算分析对该墩的承载力进行评估。结果表明:该墩裂缝属于非荷载裂缝,裂缝成因主要由大体积混凝土水化热控制、养护措施不当等多方面原因综合所致;该墩自振频率检测结果表明其横向刚度较大,满足通常值要求;评估计算结果表明,该墩承载能力满足设计要求。 Taking a certain bridge as an example, a bridge pier in the bridge is tested on site. Combined with the construction process of the pier and the local environmental conditions, the distribution and origin of cracks in the pier are analyzed in detail. The theoretical calculation and analysis of the pier The carrying capacity of the assessment. The results show that the cracks in the pier are non-load fractures, and the cause of the fractures is mainly caused by many reasons such as the hydration heat control of mass concrete, improper curing measures and so on. The natural frequency of the pier shows that the transverse stiffness is large, Value requirements; evaluation results show that the pier carrying capacity to meet the design requirements.
