Due to the carrying capacity of horizontal load

battered piles were generally used in the foundations of bridge

wharf and transmission power line. The horizontal and vertical load sharing of piles is not only force decomposition

which is related with the axial and lateral stiffness of inclined and vertical piles. The influence of axial and lateral stiffnesses coupling should be considered in the analysis of inclined group piles foundation. According to the studies of the axial and lateral stiffness of inclined and vertical piles and the analysis of load sharing of group piles

the force characteristics of battered pile foundation were gained. First

the lateral stiffness of positive inclined pile is biggest; and the lateral stiffness of vertical pile is bigger than that of negative inclined pile. Second

the influence of pile length on the axial stiffness is very significant. When the pile was lengthened

the axial stiffness was increased; and the differences between axial stiffness and lateral stiffness were expanded. Last

most of the vertical load was borne by the axial force of piles. When the ratio of axial stiffness and lateral stiffness is small

most of the horizontal load was borne by the lateral force of piles. When the ratio of axial stiffness and lateral stiffness is large

most of the horizontal load was borne by the axial force of piles. At the same time

due to the inclined angle of pile is small

the large axial force is created to resist horizontal load
