Abstract

Abstract

The original terrain elevation difference is very large in a factory of Shenzhen. In order to flat ground, we use dynamic compaction (4 000 kN·m) to consolidation of foundation soil. Revealed by dynamic penetration test (DPT), there is the level of foundation soil stratification. Depth and DPT blow count is a function of cubic or power. Its the evidence of the dynamic consolidation of foundation soil by vibration waves (mainly P-wave) have been reinforced. There is no significant hierarchical feature, between the tamper-point foundation soils.
