Abstract A hypothetical shear slip surface will be used for piecewise analysis of double-row piles. Above the shear slip surface，the volume ratio method can be used for solving earth pressure，and the below used “m” method. Then，the differential deflection of each section can be established. According to the relationship of each section and the boundary conditions，the differential equations can be solutedsolved. After fetching each deflection equations，the situation of deformation and internal forces can be achieved.

Key words： pile foundations double-row piles shear slip surface deflection differential equation earth pressure
