摘要
本文从桥梁设计技术、施工技术和预应力材料等方面简要介绍了我国预应力混凝土连续梁桥的发展，例举了具有代表性的工程实例。重点对预应力混凝土连续梁桥使用过程中存在的主要问题、形成原因以及设计对策等方面进行了初步分析和论述。
Based on the design, construction and materials, brief introduction is given to the development of PC continuous beam bridges in China, including some typical projects. Emphasis is laid on the problems caused during the service of such bridges, and initial analysis is made of the causes and countermeasures in the design.
