【Abstract】 Several computation methods of ending bearing capacity of rock-socketed pile in different condition are mainly discussed in this paper,the calculated results of ending bearing capacity from code is smaller than others,which is obtained through comparing the active technical codes with other methods concerning end bearing capacity.This paper sums up the features of the typical Q-S curves and points out the relations among and and,as well as several advice is proposed to improve the end bearing capacity.更多还原
