Compaction law of impact-like vibration

This paper selects 21 kinds of working situation and makes a lot of compacting experiments basing on impact-like vibratory roller by self-design. The experiments show that there are correspondent relationships between the compaction degree and the subsidence of soil, and the compaction times is related also. In the initial compaction with some times, the more the subsidence range of soil is large, the more the increase of compaction degree is large. But in latter process of compaction, the tendency of reduction of subsidence range is same with the increase of compaction degree, and they tend to the stable value. According to the vary law of compaction degree and dispersed curves of experiments, this paper establishes the function to describe the relationship between the compaction degree and compaction times, and checks the experiment data of 21 kinds of working situation and 4 types of the vibratory roller using Matlab programming. The results shows that the calculating values approach the measuring values, the range of relative error is from 0.2% to 6%. 3 tabs, 6 figs, 10 refs.
