为了扩大跨越管桥的构造型式范围,作者从分析现有拱式管桥不可避免的一些实际问题入手,提出一种较组合拱式管桥更为合理的新型结构——提篮半穿式管桥,论述了它的结构特性及主要计算方法,并简要地给出了按此方案所作的一项设计成果。 In order to expand the scope of the type of construction spanning the tube bridge, the author starts with analyzing some practical problems that inevitably exist in the existing arch bridge, and proposes a new type of structure that is more reasonable than the combination of the arch bridge - , Discusses its structural characteristics and the main calculation methods, and gives a brief summary of the results of a design made by this program.
