SGER: Constitutive Response of Porous or Granular Geological Materials

9988506了解土壤和岩石等岩土材料的响应对于解决岩土工程、地震工程、环境工程、交通运输、建筑和施工技术中的各种问题至关重要。地质材料力学响应的研究涉及四个主题：将现有多孔岩石的本构理论扩展为全三维理论。将速率效应（惯性和摩擦）纳入本构理论。发展速率无关和速率相关的土本构理论，包括含水饱和度的影响。这些本构理论在岩土工程和地震工程中相关初值和边值问题求解中的应用。本研究以可靠的实验数据为基础，结合微观力学分析（理论和数值）和经验主义。

9988506Understanding the response of geomaterials such as soils and rocks is crucial in addressing a variety of problems in geotechnical engineering, earthquake engineering, environmental engineering, transportation, building and construction technology.This research on the mechanical response of geological materials addresses four topics: The extension of an existing constitutive theory for porous rock into a fully three-dimensional theory. The inclusion of rate effects (inertial and frictional) into the constitutive theory. The development of rate-independent and rate-dependent constitutive theories for soils, including the effects of water saturation. The application of these constitutive theories to the solution of relevant initial and boundary value problems in geotechnical engineering and earthquake engineering.The research utilizes a combination of micro-mechanical analysis (both theoretical and numerical) and empiricism based upon reliable experimental data.
