摘　　要：跨河桥梁墩柱桩基的水流砂石冲击磨蚀问题严重危害桥梁安全。对常见的桥墩桩基防磨蚀技术进行了分析总结;在此基础上,结合山区公路桥梁工程实际给出了一种新型的防护措施——超高性能混凝土防冲刷磨蚀结构,并详细介绍了该防护结构的实施方法。该类防护相较于其他水工防护构造物来说混凝土用量更少,更加低碳环保。该研究成果可为类似的桥梁防磨蚀工程提供有价值的参考。The erosion caused by water flow and sedimentary particles poses a serious threat to the safety of bridge pier and pile foundations.This paper analyzes and summarizes common antierosion techniques for bridge pier and pile foundations.Based on this,a new protective measure is proposed using ultra-high performance concrete as an anti-erosion structure,which is applied to the practical construction of bridge projects in mountainous highways.The implementation method of this structure is introduced in detail.This type of protection has a lower concrete consumption compared to other hydraulic structures,making it more sustainable and environmentally friendly.The research results of this paper can provide valuable references for similar anti-erosion engineering projects for bridges.
