It is crucial that scientists and engineers develop their expertise and capability through research and practice to quantify the interaction of infrastructure with the surroundings and the ground upon which they are founded. Therefore, the engineering concept 'soil-structure interaction' forms an integral part of delivering successful project outcomes. As the Lead and Honorary Editor for this Special Issue, Soil-Structure Interaction, I cordially invited the submission of esteemed articles related to recent projects, research, or case studies. These articles detail how geosciences (soil, rock, ground water, geochemistry, geology, hydrogeology, surface run-off, rain, wind, and temperature) directly interact with and impact the performance of human-made structures, buildings, or infrastructure through the following aspects: i) Underground construction
ii) Innovative ground improvement methods
iii) Geological explorations and interpretation
iv) Instrumentation and field observational method
v) Use of artificial intelligence or algorithms
vi) Forensic engineering or inverse-analysis methods
vii) Geophysical methods for soil or rock characterization
viii) Advancement in laboratory and field testing of geomaterials
ix) Advancement in numerical analysis
x) Advancement in multi-disciplinary design theories, codes of practice, and engineering education.
