摘要

降雨侵蚀严重威胁土质边坡稳定，甚至

诱发失稳破坏。联合黄麻纤维与微生物诱导碳酸钙沉淀技术开展黄土坡面生态加固，模拟降雨测试分析坡面抗侵蚀性能提升程度及影响因素，利用扫描电子显微镜和能量色散X射线光谱仪从微观角度分析减缓黄土坡面降雨侵蚀作用的机制，探究减缓黄土坡面降雨侵蚀的可行手段。结果表明：添加黄麻纤维有助于提升微生物矿化黄土抗降雨侵蚀性能，尤以中高含量中长尺寸纤维的提升效果最佳；经生物矿化处理的纤维加筋黄土能显著抵抗弱降雨（6 mm/h）侵蚀，亦能短期抵抗强降雨（45 mm/h）侵蚀；强降雨条件下，抗侵蚀性能随纤维掺量的增加而提升，但提升幅度逐步降低，最大抗侵蚀性能提升为64.2%；生物胶结硬壳层厚度随纤维长度和含量的增加而变薄，C

和C

之间厚度差达2.86倍。纤维加筋微生物矿化黄土表层存在两种胶结模式：碳酸钙晶体沉淀于粒间孔隙形成的“粒间填充”模式和碳酸钙借助纤维联结包裹土颗粒形成的“裹覆胶结”模式。

Abstract

Rainfall erosion seriously threatens the stability of soil slopes and even induces failure. In this study

jute fiber and the microbial-induced calcium carbonate precipitation technique were combined to carry out ecological reinforcement of loess slopes. A simulated rainfall test was used to analyze the improvement effect and influencing factors of slope erosion resistance. Scanning electron microscope and energy dispersive X-ray spectrometer were used to analyze the mechanism of mitigating rainfall erosion on loess slope from a micro perspective

and to explore the feasible means of mitigating rainfall erosion on loess slope. The results show that: the addition of jute fiber can help to improve the rainfall erosion resistance of microbial-mineralized loess

especially for the medium and high content of medium and long size fibers; the fiber-reinforced loess treated by biomineralization can significantly resist the erosion of weak rainfall (6 mm/h) and short-term heavy rainfall (45 mm/h); under heavy rainfall conditions

the erosion resistance increases with the increase of fiber content

but the increase range gradually decreases

and the highest erosion resistance increases to 64.2%; with the increase of fiber length and fiber content

the thickness difference between C

and C

is 2.86 times. There are two cementation modes in the surface layer of fiber-reinforced microbial mineralized loess: the “intergranular filling” mode formed by the precipitation of ca

lcium carbonate crystals in intergranular pores

and the “wrapped cementation” mode of calcium carbonate formed by wrapping soil particles through fiber connection.
