摘　　要：为防治高速公路桥头跳车病害,探索利用高速液压夯实机提高桥背高填筑路堤压实度,以解决高速公路桥头跳车病害的技术有效性。依托某高速公路高填方桥路标段,从压实度、压力范围和沉降量三方面,对高速液压夯实机作业效果进行研究。结果表明利用高速液压夯实机可将近台背处填土压实度从90%提高至97%,土压力基本保持竖向传播,不易对桥台结构产生破坏影响。因此利用高速液压夯实机技术防治桥头跳车病害是切实有效的,对同类型工程具有参考价值。In order to prevent and control the vehicle jumping disease at the bridgehead of highways,this study explores the technical effectiveness of using high-speed hydraulic compactors to improve the compaction degree of high embankment filling on the bridge back,in order to solve the vehicle jumping disease at the bridgehead of highways.Based on the high fill bridge section of a certain expressway,this study investigates the operational effectiveness of high-speed hydraulic compactors from three aspects:compaction degree,pressure range,and settlement.The results show that using a high-speed hydraulic compactor can increase the compaction degree of fill soil near the back of the bridge from 90%to 97%,and the soil pressure basically maintains vertical wave transmission,which is not easy to cause damage to the bridge abutment structure.Therefore,the use of high-speed hydraulic compactor technology to prevent and control bridge head jumping diseases is practical and effective,and has reference and guidance value for similar projects.
