Abstract

Geopolymer grouting material exhibits unique advantages in karst foundation treatment, effectively improving the bearing capacity and stability of karst foundations. This paper explores the diffusion mechanism of geopolymer grouting material in karst foundations, revealing its infiltration and hardening processes between karst layers. Through the synergistic effect of physical and chemical reactions, geopolymers can quickly fill karst pores and enhance the mechanical properties of soil. Factors such as the chemical composition of geopolymers, grouting pressure, and construction technology have a significant impact on the diffusion effect. Further optimization of grouting materials and construction methods will improve the treatment effect of karst foundations. The research in this paper provides new ideas and technical paths for karst foundation treatment.
