英文摘要Cold-region slopes are exposed to severe freeze-thaw cycles, which degrade the performance of ecological protection materials and reduce their protective effectiveness. In this study, guar gum, wood fiber, and a superabsorbent polymer (SAP) were selected as modifiers to formulate three different mix ratios of ecological protection materials (S1, S2, and S3). After subjecting the materials to freeze-thaw cycles, shear mechanical tests, hydrological property tests, and microstructural analyses were performed to investigate the mechanisms underlying the performance evolution of ecological protection materials.The results indicate that freeze-thaw cycles alter the structure of ecological protection materials, resulting in performance degradation. At the macroscopic level, this is reflected in reduced cohesion and water stability, with higher initial moisture content accelerating hydrological deterioration. At the microscopic level, freeze-thaw cycling reshapes the pore structure and particle arrangement, reducing the effective contact area between particles and thereby compromising macroscopic properties. Among the tested materials, the S1 mixture (1.0 % guar gum, 3.0 % wood fiber, 0.15 % waterretaining agent), with its higher wood fiber content, exhibited the greatest resistance to freeze-thaw damage. Its reinforcing fiber network effectively preserved microstructural integrity. Using an AHP-FSE multidimensional evaluation method, cohesion, permeability coefficient, and disintegration rate were identified as the key indicators for assessing the performance of ecological protection materials, with S1 exhibiting the best overall performance. This study highlights the link between microstructural evolution and macroscopic performance under freeze-thaw cycling, providing a scientific basis for optimizing the mix design of ecological protection materials in cold-region slope protection.
