| Abstract: | Through the non-linear finite element analysis and the dust piles at the top level-load applied to simulate the expansion of lime-soil compaction pile rammed pile composite foundation of the actual working conditions.This paper analyzes expansion of the lime-soil compaction tamping along the depth direction of pile load transfer law and the soil along the pile radial pressure distribution and tamping compaction pile settlement expansion variation,and comes to that tamping compaction pile expanded the scope ... |
