Current Status and Development Trend of Research on The Interaction Mechanism Between Large Building Foundations in Goaf Sites

With the acceleration of urban development and industrialization, the construction of large buildings in goaf sites is becoming increasingly common. The goaf site has characteristics such as underground cavities and weak soil layers, which pose significant challenges to the safety and stability of the foundation of large buildings. This article aims to systematically explore the interaction mechanism between goaf sites and large-scale building foundations, analyze the current research status, and look forward to future development trends. Through a comprehensive literature review and case analysis, this article summarizes the influencing factors of goaf sites on the foundation of large-scale buildings, while elaborating on the challenges currently faced by research and proposing possible future research directions.
