摘要:为解决土体压实质量的稳定性问题,将判定稳定性问题转换为求解最佳碾压遍数,通过观察不同碾压遍数下压实特征值的变化规律,采用3σ准则-位置剔除的综合方法筛选测试数据,剔除智能压实质量评价中出现的异常特征值,建立并推导压实特征值与碾压遍数的函数模型。结合现场检测数据,将该模型与采用传统筛选数据方法得到的压实特征值与碾压遍数的函数模型进行对比分析。结果表明:该模型可靠性更高,可为评判不同土体的压实稳定性提供参考。

Abstract:To solve the stability issue of soil compaction quality, the stability problem is transformed into finding the optimal number of roller passes. By observing the variation trend of compaction characteristic values under different roller passes, a comprehensive method of 3σ-criterion-position-elimination is used to filter test data, eliminating abnormal characteristic values in the intelligent compaction quality evaluation. A function model of compaction characteristic values and roller passes is established and derived. Combined with on-site testing data, the model is compared and analyzed with the function model of compaction characteristic values and roller passes obtained using traditional data filtering methods. The results show that the model has higher reliability and can provide reference for evaluating the compaction stability of different soils.
Keywords:intelligent compaction; compaction stability; the optimal number of roller passe; 3σ-criterion-position-elimination
