你刊1964年第三期刊載了“隧道衬砌鋼拱架設計的探討”一文,讀后有几点不同的看法提出討論,很不成熟,望大家不吝指正。 (一)建筑材料与結 构形式 (1)关于建筑材料:在这方面笔者很同意編者按的意見,即鋼軌方案与型鋼方案应并存,不过文中对其各自的优缺点未作詳尽的說明,个人認为在今后修改文件中于技术交底部份应詳加說明,以便施工单位选择时有所依据。根据个人粗浅認識型鋼主要优点即可根据受力特点、設計合理的截面形式,使得材料消耗为最小,同时在結构制
Your issue of the third issue of 1964 published a “Tunnel Lining Steel Arch Design” article, after reading a few different views put forward the discussion, it is immature, hope you feel free to correct me. (A) of building materials and structure (1) on building materials: In this regard I agree with the editor’s opinion that the rail program and the steel program should coexist, but the text of their respective advantages and disadvantages are not described in detail, Personally think that in the future to modify the file in the technical part should explain in detail, so that construction companies have to choose the basis. According to the main advantages of individual rough understanding of steel can be based on the characteristics of the force, the design of a reasonable cross-section, making the material consumption is minimal, while structural
