摘　　要：为规范路基施工,以某高速公路改建工程项目为例,开展天然砂砾石路基填方压实施工技术研究。施工前,应做好路基原地面的清表、回填;采用分层填筑的方式进行填方施工。施工中,应注意做好填筑层含水量的控制;计算冲击机械在施工中的冲击能、冲击速度,设计冲击压实施工。实例应用实验结果表明:设计的施工方法应用效果良好,可以有效提高复杂地质环境下的路基填方压实施工质量,使施工后路基各项指标符合质量要求。To standardize roadbed construction,taking a highway reconstruction project as an example,research was conducted on the compaction construction technology of natural gravel roadbed filling.Before construction,the original ground of the roadbed should be cleaned and backfilled;using layered filling method for filling construction,pay attention to controlling the water content of the filling layer during the construction process;calculate the impact energy and speed of impact machinery during construction,and design impact compaction construction.The experimental results of practical application show that the designed construction method has good application effect,and this method can effectively improve the compaction construction quality of roadbed filling in complex geological environments,so that all indicators of the roadbed after construction meet the quality requirements.
