This paper analyses the application and advantages of pile foundation intelligent construction technology in pile foundation engineering in karst areas. Using the literature review method， the basic principles， methods and processes of intelligent construction technology for pile foundations are summarized， and the impact and inspiration of intelligent construction technology on pile foundation engineering in karst areas and the future development trend of this technology are further discussed. The research results show that intelligent pile foundation construction technology can achieve real-time monitoring and control of pile foundation projects in karst areas through sensors and intelligent control systems， improve the stability and safety of construction， reduce the impact on groundwater and geological environment， and improve construction efficiency and quality. The intelligent construction technology of pile foundation will achieve more comprehensive， fine， automatic， intelligent， efficient， safe， environmental protection， personalized， customized and intelligent， and make greater contribution to the sustainable development of pile foundation engineering in karst areas.
