The invention relates to a loading experiment technology of static stress and particularly relates to a loading experiment method and device for realizing axial approximate gradient static stress. Gradient static load can be applied to a solid material so that approximate gradient static stress is generated in the solid material; and the effective experiment method and device are provided for researching the corresponding mechanical properties of the material under the gradient static stress. The loading experiment method and device provided by the invention are simple and easy to operate; a plurality of types of stress gradients can be realized, such as linear gradient static stress and nonlinear gradient static stress; and a stress environment of an engineering structure (or a medium) can be relatively really simulated, so that the corresponding mechanical properties of the material can be conveniently and deeply researched. 本发明涉及静应力的加载实验技术，特别是种实现轴向近似梯度静应力的加载实验方法及装置。本发明实现了对固体材料施加梯度静荷载，使其内部产生近似的梯度静应力，为研究材料在梯
