The reinforcing mechanism and design for the macadam pile is discussed, the results of static loading test and heavy dynamic penetration test for composite ground of a soft foundation is analyzed. It is found that the reinforcing method, which uses densification by macadam pile to consolidate the soft foundation, not only improves the bearing capacity, increases the strength of the soil between piles and reduces the ground settlement, but also removes and reduces ground liquefaction.
