资料简介： PRESTRESSED CONCRETE BRIDGES
Yves Guyon remarked many years ago that there is probably no structural problem to which pre-stress can not provide solution, and o山en a revolutionary one .The diverse applications of pre-stressed concrete described recently in the technical literature and in the general press-confirm the truth of this observation .Pre-stressing is more than a technique ;It is a general principle .
The members and structures that will be described in the following pages serve to illustrate the variety of design circumstances in which pre-stressed concrete may employed advantageously .Because of space limitations, specific applications will be described only in the most general terms .However, an extensive list of references is included, which will provide an entry into the literature for those seeking details.
预应力混凝土梁桥
Yves Guyon 在许多年前谈及或许没有预应力结构不能提供解决方法的结构问 题，而且经常是革命性的。最近，在技术文学方面和在一般的新闻里描述的混凝 土预应力多种应用确认了这一观察的真实性。预应力不仅仅是一项技术，更是一 项一般的原则。
在下面的篇幅中描述和结构，举例说明在多样性的设计环境下可以有效地利用 预应力混凝土结构。由于空间的限制，具体申请只以一般的方式描述。然而，包 括一本用于参考的广泛目录，将提供那些搜寻细节的文学的途径。
