高速铁路路基连续压实质量检测指标 CMV 影响因素分析
Study on factors of continuous co mpaction measured value in subgrade of high -speed railway
摘要
Abstract
For quantitative analysis of the vibratory compaction technology parameters on the influence degree of con-tinuous compaction measured value ,based on the orthogonal experimental design,CMV was taken as the research ob-ject,the amplitude ,excitation frequency,roller speed and driving direction was selected as the factors;the continu-ous compaction check in Zhijiang construction site of Shanghai -Kunming High -Speed Railway was carried out.The results demonstrate that the amplitude,excitation frequency and roller speed have a highly significant effect on CMV, driving direction has an obvious influence on CMV;and the degree follows by:amplitude >excitation frequency >roll-er speed >driving direction.According to the coefficient of variation of CMV,determining the vibratory compaction technology parameters,which make CMV the most stable;Based on the steady -state CMV,a regression model was established to correct the CMV under the condition of the other vibratory compaction technology parameters.This pa-per provides a new method to improve the stability of the continuous compaction value.关键词
