摘要
为确保改造后衡州大道桥的通行安全,分别对3种不同改造方案进行分析对比,采用有限元方法分析不同改造方案对桥梁结构承载力的影响,以确定最优方案。并通过荷载试验的方法研究其在改造后的受力性能,最后对其承载力进行评定。结果表明:改造铺装层方案具有施工方便、费用较低的优点,且改造后结构的承载力满足要求。研究成果为类似桥梁的加固改造工作提供可靠的技术支持。
To guarantee the safety of Hengzhou road bridge after rebuilt,three rebuilding schemes were analyzed and compared.And finite element method was used to analyzed the influence of different scheme on ultimate bearing capacity of this bridge.Then the best one was confirmed.The load test method was adopted to research the mechanical behavior of this bridge after rebuilt,and its bearing capacity was evaluated.The results show that the scheme of rebuilting pavement have such advantages as easy construction,low cost,and so on.Meanwhile,it can make sure that the bearing capacity of this bridge could meet the requirements.This achievement can provide some reference for similar engineering.
