摘要

In this study, for the grouting parameter configuration requirements of fissure grouting with a polymer slurry, response surface methodology (RSM) was used to statistically predict the grouting effect, and the effects of different grouting parameters on the response variables (maximum coupling and final diffusion distance) and their interactions were investigated. Through the multiobjective optimization technique, the optimal grouting scheme for fracture reinforcement and filling was obtained by comprehensively considering the multiple effect requirement coefficients of the grouting schemes in different rock fracture structures. The filling and reinforcement effects of the optimized grouting scheme were verified through tests. The results show that within the ranges of grouting volume, fracture roughness, and fracture aperture variation, the minimum coupling degree of the optimal response fracture is 657.801 µε, and the maximum slurry diffusion distance is 2.63 m. The proposed design method can effectively predict the optimal scheme for slurry fracture grouting and provide guidance for polymer slurry fracture grouting reinforcement engineering practices.
