摘要
本文概述铁道部科学研究院40多年来对预应力混凝土技术的研究及开发情况,如基本参数研究、新材料和新结构的试验和应用、新型桥梁支座的研制等.还论及对现有桥梁的评估和加固方法.文末对铁路预应力混凝土桥梁的近期发展作了介绍.
Part of research work and development of technology of prestressed concrete carried out in China Academy of Railway Sciences in the past forty years or more is briefly reviewed, such as the research about fundamental parameters, the experiments and applications of new materials and structures as well as the development of new bridge supports. Great attention has been paid to the assesment and strengthening of existing PC bridges. Finally the recent development of long-span PC bridges on Chinese railways is introduced.
