Abstract Reference on lateral load test and numerical simulation of large diameter pipe pile by using cast-in-place concrete(PCC)，finite element model of a single pile with or without pile partner under lateral load is established. Comparison calculations show that pile partner can ensure lateral loads delivering from pile cap to foundation soil，and double reduce stress and displacement of pile. Pile partner can also make some improvement on lateral bearing characters for the pile foundation with low cap even though the modulus of foundation soil is small. When pile partner is equipped，and the connection mode between pile cap and pile changing from rigid connection to hinge joint，pile body internal force can also be drastically reduced；and pile and pile caps by distance can only be considered to meet the requirement of vertical bearing capacity or optimization design of pile foundation stiffness to reduce differential settlement. Pillow is not necessary and can be cancelled in composite foundation when pile partner is applied. The height of pile partner has little influence on internal force and displacement of pile. Under rare earthquake action，pile partner may sacrifice firstly to keep pile perform well.

Key words： pile foundations pile partner lateral load large diameter pipe pile by using cast-in-place concrete(PCC) pile foundation with low cap pillow
