Stability Control of Continuous Compaction Measurement in High-Speed Railway Subgrade
The compaction stability is of great significant for the quality control and assurance of the continuous compaction measurement in subgrade engineering. Based on the mean-variation method, the exponential function between the roller passes and the roller measurement value was modeled to calculate the compaction stability index Δμtmv. The stabilization process of the compacted soil from loose state to dense state could be well described by the modeled function. Through the results of the roller measurement values in three test field of Shanghai-kunming high-speed rail in Huaihua, Zhijiang and Loudi, different compaction stability index due to the varied construction situations was calculated using the mean-variation method and the exponential function. The result shows that the exponential function is well adaptive to different situations and this method could be developed in controlling the stability of continuous compaction measurement.
