施工参数法在碎石填料压实效果评价中的应用研究

Study on Application of Construction Parameter Method in Compaction Effect Evaluation of Gravel Packing

以某高填方工程为背景,对碎石填料进行了试验研究,分析了碎石填料的可填性及击实指标。在试验段施工过程中,研究了冲压施工参数与填料压实质量之间的关系,提出了与目标压实度对应的施工参数。通过多个试验小区对该施工参数进行可靠性分析,并利用数理统计方法对填料压实效果进行总体评价,证实了施工参数法可有效评价填料的压实质量。

By taking the high-fill works as the background herein,the gravel packing was studied by tests to analyze its availability of filling and the compaction index.In the course of construction in the test section,the relation between the impact compaction parameters and the compaction quality was studied,and then the construction parameters corresponding to the target degree of compaction was proposed.The reliability of these parameters was analyzed through multiple test plots,and the compaction effect was evaluated by means of mathematical statistics,by which the construction parameter method was proved to be valid in the evaluation of compaction quality.
