This Research Topic is Volume II of a series. The previous volume can be found here: Physico-Mechanical Properties and Treatment Technology of Hazardous Geomaterials
New materials and technologies are emerging in every branch of geotechnical engineerings, such as high-speed railway subgrade, soil improvement and remediation, underground space structure, ground energy storage, energy pile, energy geostructure, energy tunnel, tunnel waterproof engineering, and marine engineering. In addition to the common infrastructure construction materials, it also includes the treatment of hazardous geomaterials, resource utilization of industrial wastes, geopolymer materials, contaminated soils related to geoenvironmental engineering as well as other newly developed materials.
In recent years, the advancement of new materials has promoted the development of geotechnical engineering and its close intersection with other disciplines. Scholars have done fruitful work, but the understanding of many new materials is not very clear. Moreover, the external environment (e.g., heat, water, external force) borne by various materials is becoming more and more complex. The newly developed geotechnical materials involve the coupling actions of multiple fields such as physics, mechanics, chemistry and even biology. Some new technologies and specifications are still developing. For this purpose, it is necessary to investigate the mineral composition and micro-structures, physico-mechanical properties, deformation and strength evolution process, and constitutive characteristics of various geotechnical materials. The research methods include theoretical description, numerical simulation, laboratory experiments and field tests.
The Research Topic aims to bring together Original Research and Review articles on the recent developments in natural geotechnical material improvement, hazardous geomaterials, synthetic materials, geopolymer, energy geotechnical materials and contaminated soil treatment. The Research Topic welcomes theoretical, numerical, experimental, and field studies at various scales to stimulate technical and scientific interaction between professionals.
