• abstract = "This study evaluated the mechanical properties and vibration damping capabilities of a proposed grouting materials composed of perlite, rubber, and resin, focusing on their application in tunnel vibration mitigation. Experimental data together with numerical simulations demonstrated the materials' effectiveness in reducing vibrations from subway operations. Assessments of unconfined compressive strength (UCS) and modulus of elasticity showed significant influences from the material compositions on structural integrity. Genetic programming models validated these findings, providing predictive insights with high accuracy (Rsquared values of 0.995 for UCS and 0.996 for elastic modulus). In addition, a critical finding was that increased material flexibility enhances vibration damping capabilities, although compromising the UCS. This balance in material is essential for the optimal combination. The results demonstrate that the developed grouting material can significantly enhances vibration mitigation in urban subway systems and highlight the potential of advanced grouting materials to enhance urban infrastructure resilience; however, further testing is required to fully verify the findings and assess mechanical performance before practical implementation",
