Compaction stability model based on intelligent compaction eigenvalue
HUANG Xiaoluan
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.
