Experimental Study on the Bearing Capacity of Composite Pile

Based on mass test data,this paper analyzed the load transfer characters of the composite pile which is formed by inserting the prefab concrete core into the soil mixed with cement (The composite pile is called for short in the following)and compares the single pile bearing capacity and economy index of composite pile to those of concrete hole affuse pile and prefab pile on the same condition.It is concluded that the composite pile has extensive appliance prospect in multiplayer constructions.
