| Abstract (English): |
To mitigate hole collapse and drilling deviation during the construction of large-diameter cast-in-place piles in karst areas-problems arising from inadequate geological characterization, presents a Python-based modeling system. This system uses the Kriging interpolation algorithm to construct 3D stratigraphic and karst cave models with sub-meter accuracy. The system automatically analyzes the spatial distribution of karst features and the inclination of the bedrock surface at each pile location. By integrating industrial IoT technology, it transmits processed geological data via a cloud platform to the drilling terminal. This enables dynamic visualization of the spatial relationships between the drill bit, surrounding strata, and karst cavities during operation, and provides advanced intelligent warnings. This technology has been successfully applied in the construction of large-diameter cast-in-place piles in karst-developed areas, assisting rotary drill operators in intuitively perceiving geological conditions near the drill bit, reducing adverse impacts from cavities and inclined bedrock on drilling operations, thereby providing a new technical paradigm for intelligent pile foundation construction under complex geological conditions.
