双曲砖拱是苏联首创的一种新型屋盖结构,主要优点是:节约钢材、木材和水泥而且造价也较低。自1953年开始在北京、济南、上海、天津等地兴建了不少这种建筑物,其中有很多是成功的,也有很多是发生了严重问题。根据北京、天津及上海等处,双曲砖拱调查的结果,发生问题的可以归纳为:情形不太严重的或比较严重的和倒坍的三类。经过详细分析,得到可能产生裂缝或其他事故的原因,并提出今后在设计和施工中应当注意的几点意见,借供参考。总之双曲砖拱可以采用,但必须审慎,至于有振动影响的地方或土壤地基很差的地方,更应慎重考虑。
Hyperbolic brick arch is a new type of roof structure pioneered by the Soviet Union. The main advantages are: saving steel, wood and cement and lower cost. Since 1953, many such buildings have been built in Beijing, Jinan, Shanghai and Tianjin. Many of them are successful and many have serious problems. According to the survey results of the hyperbolic brick archways in Beijing, Tianjin and Shanghai, the problems that can occur can be summed up as follows: Less severe or more serious ones and collapsed ones. After detailed analysis, we can get the reason of possible cracks or other accidents and put forward some suggestions that we should pay attention to in the design and construction in the future for reference. In short hyperbolic brick arch can be used, but must be cautious, as a place where the impact of vibration or soil where the foundation is poor, should be carefully considered.
