摘　　要：基于工程建设需要,对较天然土料性质更加稳定、可控的人工砾石土的压实度快速检测方法进行了研究。通过研究提出:人工砾石土压实度检测可以通过“砾石含量与最大干密度的关系曲线”或“砾石含量与压实干密度的关系曲线”进行快速判断,经试验验证和现场利用得出该方法可靠有效,大大缩短了检测时间,产生了较好的经济效益。同时,利用该方法进行人工砾石土的压实度检测,必须保证天然土料、人工砾石及人工砾石土性质的稳定,以及施工工艺、检测方法的相对固定,一旦以上任何一项发生变化,须进行预控线的重新建立。该方法在同类工程中具有推广借鉴意义。Based on the needs of engineering construction,this article studied the rapid detection method of compaction degree of artificial gravel soil,which has more stable and controllable properties than natural soil materials.Through research,it is proposed that the compaction degree detection of artificial gravel soil can be quickly determined through the relationship curve between gravel content and maximum dry density or the relationship curve between gravel content and compacted dry density.After experimental verification and on-site use,this method had been proven to be reliable and effective,greatly reducing the detection time and generating good economic benefits.At the same time,when using this method to test the compaction degree of artificial gravel soil,it was necessary to ensure the stability of the properties of natural soil,artificial gravel,and artificial gravel soil.At the same time,the construction process,testing method,etc.must also be relatively fixed.Once any of the above changes,the pre control line must be reestablished.This method had promotional and reference significance in similar projects.
