摘要

为明确陡立边坡生态修复植生层的有效组成及其性质在冻融环境下的演化规律，结合陡立坡面附着试验及植生试验优化植生层配比，通过直剪试验明确冻融条件下土体黏结特性的变化.结果表明，生物炭可提升土体植生性能；添加黏结剂、保水剂后，聚丙烯酰胺的加入不利于植物生长.最优植生层组成为0.8%海藻多糖、1%羧甲基纤维素、1.5%生物炭.冻融20次后基质土黏聚力损失率是重构植生层黏聚力损失率的1.27~2.93倍.低含水率条件有利于冻融过程中土体黏结特性的维持.黏结剂和保水剂形成的胶结结构有效维持了重构植生层的稳定性，使其抗冻融劣化能力显著优于基质土.该成果可为季冻区陡立边坡生态修复基材配比及工程防护提供理论依据.

Abstract

To clarify the effective composition of the vegetation layer for ecological restoration of steep slopes and the evolution patterns of vegetation layer properties under freezing-thawing conditions

the changes in soil cohesion characteristics under freezing-thawing conditions were clarified through direct shear tests

combined with the attachment test on the steep slope surface

vegetation test and the optimized vegetation layer ratio. The results show that biochar can improve the vegetation performance of the soil; the addition of polyacrylamide is not conducive to plant growth after adding binder and water-retaining agent. The optimal vegetation layer composition is 0.8% seaweed polysaccharide

1% carboxymethyl cellulose

and 1.5% biochar. After 20 freeze-thaw cycles

the loss rate of soil cohesion in the substrate soil is 1.27-2.93 times that of the reconstructed vegetation layer. Low water content conditions are conducive to maintaining the soil cohesion characteristics during the freeze-thaw process. The cohesive structure formed by the binder and water-retaining agent effectively maintains the stability of the reconstructed vegetation layer

and its anti-freeze-thaw deterioration ability is significantly better than that of the substrate soil. The findings can provide a theoretical basis for the material ratio of ecological restoration vegetation layer and engineering protection for steep slopes in the seasonally frozen areas.
