Based on the reconstruction project of Banqiao Township to Xiaoyuanzi( Ganning Boundary) second-class road on G309 line, field test was conducted to determine the construction parameters of high-speed hydraulic compactor in the reinforcement and compaction of the abutment back loess roadbed. The main factors influencing the reinforcement effect of high-speed hydraulic compactor are the ramming gear the number of ramming times and the distance between ramming points. Ba asea on the test results, the influence of different factors on the ramming effect is studied. The quality control standard of backfilling high-speed hydraulic compactor to reinforce roadbed is put forward, which is of great significance for guiding the construction of the roadbed behind the 基金项目:甘肃路桥建设集团科技项目(2017-01) (c)1994-2019ChinaAcademicJournalElectronicpUblishingHouse.Allrightsreservedhttp://www.cnki.net台背回填高速液压夯实机补强路基质量控制标准1 朱家剑 1 王选仓 3 苟想伟 2 付林杰 3 （1.公路建设与养护技术、材料及装备交通运输行业研发中心（甘肃路桥建设集团有限公司），甘肃 兰州 730030； 2.甘肃路桥第三公路工程有限责任公司，甘肃 兰州 730030； 3.长安大学，西安 710064） 摘 要： 基于波体特性的夯击能传递原理，研究使用高速液压夯实机对台背回填进 行补强夯实作业的最佳施工参数。依托 G309 线板桥乡至小园子（甘宁界）二级路 改建工程，对高速液压夯实机在台背黄土路基补强夯实中施工参数的确定进行现场 试验研究。提出了影响高速液压夯实机补强路基效果的主要因素为夯击档位、夯击 次数和夯点间距。进而根据现场试验结果，研究了不同因素对夯击效果的影响，提 出了台背回填高速液压夯实机补强路基质量控制标准，对指导台背路基工程施工具 有重要意义。 关键词： 路基工程；台背回填土压实；高速液压夯实机；施工参数 中图分类号：U416.1 Quality control standard for reinforcing subgrade of high-pressure hydraulic compaction machine with back-filling Zhu Jia-jian1，Wang Xuan-cang 3，Gou Xiang-wei2 , Fu Lin-jie3 (1.Research and Development Center of Transport Industry of Technologies, Materials and Equipments of Highway Construction and Maintenance(Gansu Road & Bridge Construction Group Co.,Ltd.) 2.Gansu Luqiao Third Highway Engineering Co., Ltd., Lanzhou 730030, China; 3..
