Study on the Application of Elastic Wave CT Technique to Detect the Effect of Post-Grouting of Pile Foundation

The post-grouting technology can effectively improve the bearing capacity and reliability of foundation piles, it is great academic economic significance to evaluate effect post-grouting. However, in general, evaluation slurry on piles still relatively single, most researchers only test improvement characteristics but there are few research results distribution state consolidation range reinforced soil. In this paper, elastic wave CT was used detect bridge Taizhou Bay Du Xiaipu Bridge, applied detection experimentally. spatial underground grouting reinforcement area were revealed from perspective visualization, influencing factors inversion analyzed. conclusions obtained similar those electromagnetic CT, laws basically consistent with current engineering experience, reflecting applicability using pile foundation.
