高速公路隧道桥梁加固技术研究

摘要

分析了隧道施工对高速公路桥梁的影响，从粘贴加固法、改变结构体系法、增设纵梁加固法等方面，阐述了常见的桥梁加固技术，为桥梁加固改造方法的选择提供了依据。%The PaPer analyzes the influence of the tunnel construction on bridges of exPressways,and illustrates the common bridge reinforcement technique from the strengthening with external bonding,alteration structural system method,and additions of longitudinal beam reinforcement method,so as to Provide some reference for the selection of the reinforcement reconstruction methods of bridges.
