摘要
针对框架桥下穿既有铁路施工风险产生的原因进行综合性分析,如防护不到位、吊车臂侵限、点前超前、超限、盲目开挖及注浆等,并结合具体的工程实例,明确该工程项目的重点和难点内容,提出框架桥下穿既有铁路施工风险监控措施,希望可以为类似工程项目提供有效借鉴。
This paper mainly analyzed the causes of the construction risks of the existing railway crossing under the frame bridge,such as inadequate protection,crane arm invasion,ahead of the point,over limit,blind excavation and grouting,etc.combined with specific engineering examples,the key and difficult contents of the project were clari fied,and the monitoring measures for the construction risks of the existing railway crossing under the frame bridge were proposed,hoping to be similar projects provides effective reference.
