碎石土回填施工质量控制指标分析

Analysis on the quality control index of the gravel soil backfill

在分析碎石土干密度、碎石掺量比及碎石土中土体干密度相互关系的基础上，提出了碎石土回填施工质量的评价方法和控制指标，并推荐使用碎石土中土体干密度（压实度）这一指标评定其回填质量。

Based on the analysis on the relation among the gravel soil density, gravel content and dry soil density, it provides the assessment method and control index of the gravel soil backfill, and recommends dry soil density to assess the backfilling quality.
