摘　　要：随北京市政基础交通建设的高速发展,地下工程的建设可能会对施工范围内既有城市道路桥梁产生安全风险,特别是在交通条件复杂、采用暗挖法施工的轨道工程项目中,因此对被穿越的既有道路桥梁设施进行加固显得尤为重要。研究介绍了穿越工程工后加固实例的实施依据、施工措施、监测手段等,总结了加固工程施工实践经验。With the rapid development of Beijing’s municipal infrastructure construction,the construction of underground engineering may pose safety risks to existing urban roads and bridges within the affected area,especially in the construction environment of track engineering with complex traffic conditions and the use of underground excavation methods.Therefore,it is crucial to take reinforcement measures for the crossing of existing road and bridge facilities.This study introduces the implementation basis,construction measures,monitoring methods,etc.of post construction reinforcement examples for crossing engineering,and summarizes the practical experience of reinforcement engineering construction.
