摘　　要：对既有桥梁的加固是桥梁建设可持续发展的重要举措,预应力技术由于其显著的优势,在桥梁加固工程中得到了广泛的应用。文中在简要介绍预应力加固原理与设计要点的基础上,结合申杭线大桥加固工程,重点介绍了体外预应力技术在桥梁上部结构加固中的应用。Bridge strengthening is an important measure for sustainable development of bridge construction. Due to its significant advantages, prestressing technique has been widely used in bridge strengthening. On the basis of the brief description on principal and design features of prestressing technology, taking the strengthening of Shen-hang project as an example, this paper mainly presents the prestressing technology application to bridge superstructure.
