重点研究了无铰拱桥受力特性,并以重庆双龙堡大桥为例,介绍了大桥产生的缺陷和病害,分析了缺陷产生的原因,将桥梁外观检查与分析计算方法二者相结合,尤其通过对大桥上部主要承重结构技术状况进行了深入分析和评定,提出了具有针对性的维修措施和养护建议,为大桥及时、合理、科学的养护提供了理论依据,为此类典型桥梁结构上部技术分析评定提供了参考。
The stress characteristics of the hingeless arch bridge are studied emphatically. Taking Chongqing Shuanglongbao Bridge as an example, the defects and defects of the bridge are introduced. The causes of the defects are analyzed. The bridge appearance inspection and analysis and calculation method are combined, The technical condition of the main load-bearing structure in the upper part of the bridge is analyzed and evaluated in depth, and some targeted maintenance measures and suggestions are proposed to provide a theoretical basis for the timely, reasonable and scientific maintenance of the bridge. For the technical analysis of the upper part of the typical bridge structure Evaluation provides a reference.
