Experimental Research on Column-hammer Thrusted-expanged Piles in Weak Subgrade Reinforcing Project

Sun Hong-bing,Zhao Hong-bing  
Through comparison and selection test of tamping energy and cushion thickness,research on correlations and their optimizations of parameters and the relation between tamping energy,cushion thickness and cumulative settlement of dynamic compaction,it was practicable to treat weak subgrade with column-hammer thrusted-expanged piles.The testing results showed that this method could meet the technical requirement and provide guidance for similar projects.
