大洲桥为湖南省常德——安乡公路上单孔孔径10米的无筋波纹薄壳拱桥,是在文化大革命取得伟大胜利的一九六七年三月设计施工修建的。无筋波纹薄壳拱的材料省、安装简易、不需要钢材,是一种较为经济的轻型结构,有利于缺料的软质地基建桥;它能充分利用断面的强度,砌体小,重量轻,也为拱桥走向更轻型结构提供一个方向。由于这种无筋波纹薄壳拱桥还是第一次试验,我们学习马列主义、学习毛泽东思想很不够,业务水平低,不论是设计上或施工上都很不成熟,错误之处,希望同志们指正。
The Bridge on the Continent is a non-corrugated thin-walled arch bridge with a single hole diameter of 10 meters on Changde-Anxiang Road in Hunan Province. It was designed and constructed in March 1967, which achieved great victory during the Cultural Revolution. Rib-free thin-walled arch arch material province, easy to install, do not need steel, is a more economical light structure, is conducive to the lack of soft ground foundation bridge; it can take full advantage of section strength, small brick, light weight , But also provide a direction for the arch to a lighter structure. Since this kind of non-corrugated thin-walled arch bridge is still the first experiment, we study Marxism-Leninism, study Mao Zedong Thought is not enough, business is low, both design and construction are immature and mistakes, I hope comrades correct .
