一、关于预应力混凝土修建斜拉桥的前景MOREAU 先生说:斜拉桥的结构形式是非常多种多样的,它可供工程师们实地合理地广泛选择,与吊桥相比,它具有无可争议的优越性,因为其结构断裂安全性强、空气动力稳定性好,近年来已被普遍承认。长期来,由于予应力最新领域的技术经验曾一度缺乏,人们并不很喜欢用混凝土结构,然而,钢结构斜拉桥却存在着一些不可忽视的缺点:

First, on the prospects of building prestressed concrete cable-stayed bridge MOREAU said: cable-stayed bridge structure is very diverse, it allows engineers to choose a wide range of reasonable and on the ground, compared with the drawbridge, it has no doubt The superiority of the structure because of its structural fracture safety, aerodynamic stability is good, in recent years has been generally recognized. For a long time, due to the lack of technical experience in the latest fields of prestressed stress, people do not like to use concrete structures, however, there are some shortcomings that steel structures can not be ignored:
