公路桥梁桥头跳车病害成因与新型处治技术的应用研究

Research on Causes and Application of New Treatment Technologies for Bridgehead Jumps in Highway Pavements

摘要

随着我国公路网络的不断完善，桥头跳车病害日益突出，严重影响桥梁服务性能和行车安全。跳车现象导致车辆冲击加剧、路面损坏，并可能引发桥梁附属设施受损。本文梳理了桥头跳车的表现及危害，深入分析地基不均匀沉降、填土压实度不足、结构连接设计不合理和车辆荷载冲击等主要成因。针对传统治理手段的不足，重点探讨了地基加固、复合材料填充、结构优化与智能监测等新型处治技术，并结合工程案例总结了应用成效。最后，提出“工程预防为主、智能治理结合”的系统对策，为桥头跳车病害的高效治理提供理论与技术参考。

Abstract

With the continuous improvement of China’s highway network, bridgehead jumps have become increasingly prominent, severely affecting bridge service performance and traffic safety. This phenomenon intensifies vehicle impacts, damages road surfaces, and may lead to damage to bridge ancillary facilities. This paper examines the manifestations and hazards of bridgehead jumps, conducting an in-depth analysis of key causes including uneven foundation settlement, insufficient soil compaction, improper structural connection design, and vehicle load impacts. Addressing the limitations of traditional remediation methods, this study focuses on new treatment technologies such as foundation reinforcement, composite material filling, structural optimization, and intelligent monitoring. Case studies from engineering projects summarize the application outcomes. Finally, a systematic strategy combining “prevention-oriented engineering and intelligent governance” is proposed, providing theoretical and technical references for efficient management of bridgehead jump defects.
