In view of the problems of large discreteness

poor timeliness and insufficient adaptability to complex geology existing in the traditional foundation detection methods

this study systematically discusses new technologies such as 3D quantification of geological radar defects

real-time monitoring of static pressure pile construction and artificial intelligence(AI)data fusion.The effectiveness of the technology is verified by laboratory model tests and typical engineering application cases.The comparison of technical indicators shows that the new method has significant advantages in efficiency

accuracyand economy

which provides effective support for engineering safety control.
