Geotechnical engineering serves as the foundation $($quite literally$)$ of civil engineering projects, encompassing soil mechanics, foundation design, and earthwork analysis. Explore the intricate relationship between soil behavior, geological formations, and engineering interventions in the context of constructing stable foundations for various structures. How do engineers assess soil properties and potential hazards, such as liquefaction or landslides, to inform site selection and foundation design? Additionally, examine the role of advanced technologies, like remote sensing and geophysical surveys, in enhancing our understanding of subsurface conditions and optimizing construction practices. Consider the broader implications of geotechnical engineering on urban planning, infrastructure resilience, and environmental sustainability, citing relevant research findings or industry trends to support your arguments.
