Abstract
This paper combined with the practice of geotechnical testing regulations,based on a Jiangsu highway expansion project of subgrade soil random sampling test data,it compared and analyzed the two kinds of solving methods of compaction,and used the quadratic fitting curves method to solve compaction index of mixture with different lime content, preparation and compaction methods. Results show that:it’s suggested to use the three point two interpolation method or the two curve fitting method to solve the best compaction index of subgrade soil indicators. In order to ensure the reasonable compaction effect and avoid the maximum dry density being false partial large or the compaction degree being false partial small,the n-power of curve fitting should not be too high;When the lime content increased from 0 to 8%,the optimal water content was decreased in a trend of quadratic curve,the maximum dry density was increased in a trend of cubic curves;compared to the undisturbed soil,the maximum dry density of compacted soil is relatively larger,while the optimum moisture content is smaller;compared with light hammer, the maximum dry density of heavy compaction is much larger,while the optimum moisture content is much smaller.关键词
