摘要

[目的] 探究添加不同浓度的改性亲水性聚氨酯树脂(W-OH)溶液对砾石石渣坡面渗漏的改良效果，为改良粗粒石渣的渗漏性能，减少其水分漏失以及石漠化地区植被恢复提供理论支撑。[方法] 以广西石漠化地区某公路石渣边坡为研究对象，在边坡现场采用不同的来流量对添加不同浓度W-OH溶液的石渣坡面开展人工径流入渗试验。[结果] 未经W-OH溶液处理的边坡渗漏严重，当来流量大于30 L/min时可形成坡面径流。且来流量为30 L/min时径流率仅占来流量的18.3%，有81.7%的水从坡体渗漏流失。经W-OH溶液处理后坡面的稳定径流率和稳定入渗率均随来流量和W-OH溶液浓度的增大而增大。用3%~6%浓度的W-OH溶液处理后坡面的稳定径流率较未处理坡面提高了200%~385.5%，且W-OH溶液的浓度越高，对坡面的处理效果越好。入渗径流比随来流量和W-OH溶液浓度的增大而减小。[结论] 采用W-OH溶液处理后可有效减少粗粒石渣边坡的渗漏量，提升坡体的保水能力，有助于边坡植被的修复。

Abstract

[Objective] The use of modified hydrophilic polyurethane resin binder (W-OH) solution at different concentrations to reduce leakage from gravel slag slopes was investigated to provide theoretical support for reducing leakages from coarse gravel slag and to improve vegetation restoration in rocky desertification areas. [Methods] A highway slag slope in the rocky desertification area of the Guangxi Zhuang Autonomous Region was investigated. Artificial erosion experiments were conducted on a sloping gravel surface and the treatments were different concentrations of added W-OH solution with different erosion flow rates. [Results] The slope that was not treated with the W-OH solution produced large amounts of leakage water and runoff on the slope only appeared when the scouring discharge was greater than 30 L/min. When the scouring discharge was 30 L/min

the runoff rate accounted for 18.3% of the incoming flow rate and 81.7% of the water was lost due to slope leakage. However

the average runoff and average infiltration rates for the slope after treatment with the W-OH solution increased as the inflow rate and W-OH solution concentration rose. The stable runoff rate for the slope treated with W-OH solution concentrations of 3%—6% increased by 200%—385.5% compared to that of the untreated slopes and the higher the concentration of the W-OH solution

the better the treatment effect on the slope. The infiltration runoff ratio decreased as the inflow rate and the W-OH solution concentration increased. [Conclusion] Treatment with the W-OH solution effectively reduced leakage from coarse-grained slag slopes and improved the water retention capacity of the slope. These improvements contributed to slope vegetation restoration.
