Model Tests on the Layout of Punning Position in Dynamic Compaction for Loess

Abstract:

To find the influence of the layout of punning position in dynamic compaction for loess, four model tests are performed, which equal in the tamping energy but differ in the layout of punning position. In model tests the settlement, the dry density and the shear strength parameters of the soil samples are measured and analysis of the effects of different test plans is made. The test results manifested that the decrease of the distance between the pounding points might result in an increment of the settlement, the dry density and the cohesive strength but not the angle of internal friction. And from the comparison of the test results, a more efficient layout of punning position is given.
