The invention discloses a stress dispersion nested steel pipe pile. According to the stress dispersion nested steel pipe pile, vertical loads are respectively transferred through multiple layers of steel pipes, so that the stress dispersion ranges of single piles in the foundation are increased to improve the bearing capacity. The stress dispersion nested steel pipe pile is capable of effectivelyimproving the single pile bearing force and is stable and controllable in quality, strong in long-term anti-corrosion performance, convenient to construct and high in performance-cost ratio. 本发明公开了一种应力分散套叠钢管桩，通过多层钢管分别传递竖向荷载，增大单根桩在地基中的应力扩散范围以提高承载力。本发明有效提高了单桩承载力，质量稳定可控，长期抗腐蚀性能强，施工方便，性价比高。
