摘要：

Grouting technology is now widely used in the construction and operation & maintenance of geotechnical engineering projects because of its significant advantages in the management of disasters such as seepage, sudden water and mud, and soft soil reinforcement. The dam foundation grouting technology is explained from the perspectives of the theory of groutability analysis based on the fractal geometry of the fractured rock mass and the fuzzy RES-cloud model, new materials for polymer and microbial grouting, 3D model visualization and virtual-real coupling computer technology, and consider the grout diffusion model, the viscosity time variation law and structural characteristics of grouting complex to discuss and analyze the grouting technology of shield tunnel and subsea tunnel, finally, the principle of post-grouting reinforcement of pile foundation and load-settlement characteristics are explored and summarized. The application of grouting technology in the construction of geotechnical engineering series of projects will certainly improve the engineering quality of geotechnical projects in all aspects.
