摘要
预应力混凝土连续梁桥在中、小跨径及一般大跨径桥梁中一直占有主导地位,发展前景广阔。我国近几十年来在预应力混凝土梁桥的建设方面虽然取得了很大的进步,但在设计、施工和新材料应用方面的整体技术水平还有待进一步提高。通过对国外预应力混凝土连续梁桥发展趋势及施工技术研究,了解国际桥梁的先进设计理念及施工技术,对投标国外工程项目时制定合理的施工方案,增强国内企业拓展海外桥梁施工市场的竞争力,提供有益的借鉴。
The prestressed concrete(PC) continuous beam bridges have been playing a leading role in the construction of medium span,small span and commonly long span bridges and the vistas of development of the bridges is yet vast.In the recent several decades,though great achievements have been made in China in the construction of the PC continuous beam bridges,the global techniques of the bridges in the country in the filed of the design,construction and new material application remain to be further improved.The study of the development trend and construction techniques of foreign PC continuous beam bridges and the understanding of the advanced design concepts and construction techniques of the bridges can provide domestic enterprises with helpful reference for formulating their rational construction schemes in bidding foreign bridge projects and for reinforcing their competitive power in developing bridge construction markets abroad.
