摘　　要：在实施黄河流域生态保护和高质量发展重大国家战略及交通强国战略的背景下,沿黄高速公路建设发展迅速,黄河泥沙以其作为路基填料的潜力备受关注,黄河泥沙的路用性能与改性利用研究成为热点。化学改良、生物矿化加固和高聚物加固技术均被认为能够有效改善黄河泥沙的工程特性,其中:化学改良手段(如碱激发技术)加固黄河泥沙技术上可行,但相关研究多关注于黄河泥沙碱激发制备砖砌体;生物矿化技术是目前岩土工程领域的研究热点,现有研究证实生物矿化技术适用于黄河泥沙,且相比微生物诱导碳酸钙沉淀(MICP)技术,脲酶诱导碳酸钙沉淀(EICP)技术因其游离态脲酶的小分子尺寸更易穿过黄河泥沙孔喉而适用性更好;高聚物加固黄河泥沙的力学和耐久性表现均表明其应用潜力值得挖掘。基于此,对黄河中下游泥沙来源和分布数据进行整合梳理,分析黄河泥沙的理化特性,并系统阐述黄河泥沙的路用性能研究进展。黄河泥沙应用于路基工程的可行性已经得到初步验证,绿色环保的生物矿化加固技术将进一步支撑黄河泥沙作为路基填料的可行性。基于现有工程体系的不断完善、多学科交叉的深化,黄河泥沙生态资源的利用潜力将被充分开发释放。Under the implementation of the major national strategy of ecological protection and high⁃quality development of the Yellow River Basin as well as the transportation power strategy,the construction of highways along the Yellow River is developing rapidly.The Yellow River silt is attracting attention for its potential as roadbed filler.Research on road performance and modified utilization of Yellow River silt becomes a hot issue.Chemical improvement,biomineralization reinforcement and polymer reinforcement techniques are considered to be effective in improving the engineering properties of Yellow River silt.Chemical improvement(e.g.,alkali excitation technology)to reinforce the Yellow River silt is technically feasible.Still,the related research mostly focuses on the preparation of brick masonry by alkali excitation of Yellow River silt.Biomineralization technology is currently a research hotspot in the field of geotechnical engineering and the applicability of biomineralization technology to Yellow River silt has been confirmed by existing research.Compared with Microbial Induced Calcium Carbonate Precipitation(MICP)technology,Enzyme⁃Induced Calcium Carbonate Precipitation(EICP)technology has better applicability due to the small molecule size of free urease that is easier to pass through the pore throats of the Yellow River silt.The mechanical and durability performances of polymers reinforcing Yellow River silt indicate its application potentials are worth exploring.Based on this,the silt source and distribution data of the middle and lower reaches of the Yellow River Basin were integrated by this paper.The physical and chemical properties of Yellow River silt were summarized,and the research progress on road performance of Yellow River silt was systematically described.The feasibility of applying Yellow River silt to roadbed engineering had been preliminarily verified.The feasibility of Yellow River silt as roadbed filler will be further supported by green biomineralization reinforcement technology.Based o
