从山东临清运河大桥的50公尺跨径装配式钢筋混凝土系杆拱主孔的施工中,接触到了不少值得商榷的问题。兹就笔者现阶段体会所及,对于此种桥型结构有关。设计与施工方面的若干问题,提出一些不成熟的看法,以供各方面的参考。关于设计方面通过施工,除已发现我设计图纸上的一些差错小节(如抗风构钢筋尺寸注错与若干钢筋长度计算错误等)外,尚有下列几个比较基本的问题需要商榷: 一、装配式钢筋混凝土系杆拱桥的合理结构型式:
From the Linqing Canal Bridge in Shandong 50-meter span of the assembly of the main span of the reinforced concrete arch arches, touched a lot of questions to be discussed. I hereby understand the author at this stage, for such a bridge-type structure. Design and construction of a number of issues, put forward some premature views for all aspects of reference. On the design aspects of the construction, in addition to some of the errors I have found on the design drawings (such as wind-resistant steel structure size error and a number of reinforcement length calculation error, etc.), there are several more basic issues to be discussed: First, Assembled type of reinforced concrete tied arch reasonable structure type:
