About this Research Topic
Geomaterials are one of the most common materials in the world. According to the functions, the geomaterials can be divided into different types, such as soft soil, granular aggregates, and composite materials. However, with the development of underground engineering to the deeper part of the Earth, the mechanical properties, no matter what kind of geomaterials, will change after being subjected to multiple environments, including temperature field, stress field, seepage field, and chemical field. These changes may cause catastrophic damages to underground structures, leading to economic losses and casualties.
With regard to multi-factor coupled interactions, extant studies on the characteristics of mechanical behaviors of deep geomaterials and the control theory of multi-field coupling have manifested keen interests in the field of geology all over the world. In order to ensure the stability of geomaterials under multi-field coupling, a growing body of investigations has been conducted, which encompasses theoretical analysis, analytical analysis, numerical simulation, simplified analysis, laboratory test, and field work. It is thus of prime importance and necessity to understand the mechanical behaviors and rheological properties of geomaterials under different coupling conditions.
This Research Topic aims to present and disseminate recent advances in the dynamic response of geomaterials under multi-field coupling. We welcome theoretical, experimental, and numerical Original Research and Review articles to address the following themes that include, but are not limited to:
• Mechanical models of geomaterials
• Local/non-local deformation in geomaterials
• Strength and deformation characteristics of geomaterials under multi-field coupling
• Failure mechanisms and risks of geomaterials in tunneling, mining, slope, and dam
• Field investigation of deep geomaterials and associated geological disasters
• Numerical simulation of deep geomaterials and associated geological disasters
• Scaled model test with analogy materials
• Sustainability in geomaterials
