THE BEARING CHARACTERISTICS OF PRESSURE GROUTING PILE AND EVALUATION OF ITS BEATING CAPACITY

Pressure grouting pile is a new kind of grouting pile,whose bearing capacity made up end bearing and side friction.The pressure grouting pile has higher bearing capacity than other kinds of grouting pile,and it consists principally in frictional resistance.65%~75% of ultimate bearing capacity of pressure grouting pile comes from the side friction based on analyzing the proportion of frictional resistance to end bearing.
