Experiment Research of the Lateral Properties and Density Variation of Loess Subgrade to Dynamic Compaction for Mountainous Highway

Abstract:

To study the applicability of dynamic compaction for loess subgrade, the model test had been done. According to the test results, some conclusions were drawn out as follows: dynamic compaction can improve the density of loess in a short time, the lateral effective compaction width of loess was narrowed with the depth of loess deepened. In the same depth of soil, the density was improved with the tamping times, and the lateral compaction width was relevant to the distance between tamping pit and discussing spot.
