This research will investigate the contact problem between structures and geologic materials subjected to static and cyclic loading. A continuum mechanics model will be developed which will include many relevant phenomena such as state of stress and strain, hardening an softening, fluid pressure in the geologic material, and deformation modes. Experimental techniques will be used to determine material constants and to verify the model. The result of this research can be used in the design of structures founded on geologic materials subjected to earthquake loading.

这项研究将研究结构和经过静态载荷的地质材料之间的接触问题。 将开发一个连续力学模型，其中将包括许多相关现象，例如应力和应变状态，在地质材料中加强软化，流体压力以及变形模式。 实验技术将用于确定材料常数并验证模型。 这项研究的结果可用于设计基于地震载荷的地质材料的结构的设计。
