Aiming to propose a rational hybrid foundation that is able to decrease the response of structures subjected to an earthquake, a new goematerial with high damping performance that is able to be used as a planting base was developed, and the response simulation analysis of the foundation was executed. As a result, it is turned out that the stress-strain relation of the material in the range to large strain (approx. 15%) is linear and has not a clear yield point. In addition, strength of the material increases by the confining pressure load. Moreover, the effectiveness of the response decrease of the proposed hybrid foundation was verified through the simulation analysis.

为了提出一种能够降低结构在地震作用下反应的合理的混合地基，研制了一种新型的高阻尼性的可用作种植基础的材料，并对其进行了反应仿真分析。结果表明，该材料在大应变范围内的应力-应变关系(约.15%)是线性的，没有明确的收益点。此外，材料的强度随着围压载荷的增加而增加。通过仿真分析，验证了所提出的混合地基的减振效果。
