铁路桥梁基础冲刷监测技术与安全评估研究
Research on Railway Bridge Foundation Scour Monitoring Technology and Safety Assessment
摘要
Abstract
The frequent occurrence of railway bridge disasters caused by foundation scour has become a significant threat to the safety of wading railway bridge structures.In order to ensure the safe operation of railway bridges,real-time monitoring of bridge foundation scour and structural safety assessment are particularly important.This paper summarizes the application status and development trend of foundation scour monitoring technology and safety assessment method in the field of railway bridge structure safety.It focuses on the application and innovation of dynamic characteristic measurement technology in bridge safety monitoring and safety assessment.The core concepts,key methods,and main characteristics of related technologies are systematically analyzed.On this basis,a bridge safety monitoring scheme based on dynamic characteristic analysis is proposed,and a 30-day continuous monitoring is carried out on a ballastless track high-speed railway simply supported beam bridge project in southwest mountainous area.The implementation results show that the monitored bridge response has obvious changes at the pile cap,and reaches the peak values of 0.0939 m/s2 and 0.1202 m/s2 respectively in the direction of train and water flow.The monitoring data are within the normal range,which can provide solid data support for the accurate evaluation of bridge structure safety,providing reference for the design and safe operation and maintenance of the whole life cycle of railway bridges.关键词
