| 摘 要： | 随着社会经济的发展、人们生活水平的提高,运输数量和重量的加大,对于公路的荷载等级要求也不断提高,而我国现有的大多数公路桥梁的设计标准较低,随着桥龄的增长,老化和破损现象比较严重,或多或少的存在承载力不足的情况,难以满足现阶段的交通运输要求.本文在对我国近几十年来在混凝土梁桥体外预应力加固技术上所取得的成果进行学习、研究和总结的基础上,遵循桥梁加固、改造工作的共性,结合具体桥梁的特殊性,对T形梁桥的加固改造技术和施工工艺进行研究,以期对同类桥的加固维修和体外预应力桥梁设计提供一些参考.

| Abstract: | With the development of the social economy and improvement of the living standard, the increase of transportation quantity and weight lifts the bar for road load rating. However in our country, most roads and bridges were designed under low standards. Serious aging and broken conditions occurred with increasing age and more or less posed insufficient bearing capacity, which could hardly meet the transport requirements. This is going to research the reinforcement and construction technologies through studying existing achievement of external prestressed rein- forcement technology of concrete beam bridges in the past decades of our country, for the purpose of providing some references to designs for similar bridges. |
