Abstract: The practices show the constructional methods of turning arch have special superiorities in some conditions, which are similar to that of the first turning constructional arch in our country. Directing to the shortages that are in large numbers, of masonry for balance weight and absorbing the advantage of the design suggested by B. Д. Baсильев, the meditation of arch bridge in flying bird balance by itself in respect to the turning construction and primary design are presented. In addition, the comparisons of several turning consttuctional methods are given.

摘要： 转体架设拱桥的实践表明,在一定条件下有其独特的优越性。本文利用与国内第一座转体架设拱桥相似的自然条件,针对现行设计中存在的平衡体圬工量大的缺点,吸取B. Д. Baсильев建设方案的优点,提出飞鸟式自平衡转体架设拱桥的构思,并进行了初步设计,以此与现有几种拱桥转体施工法进行比较。
