黄河泥沙的路用性能与改性利用研究进展
Research Progressand Review of Road Performance and Modified Utilization of Yellow River Silt
摘要
Abstract
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 Riv-er silt is attracting attention for its potential as roadbed filler.Research on road performance and modified utilization of Yellow River silt be-comes a hot issue.Chemical improvement,biomineralization reinforcement and polymer reinforcement techniques are considered to be effec-tive 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 Carbon-ate 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 de-scribed.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 on the continuous improvement of the existing engineering system and the deepening of multidisciplinary crossover,the utilization potential of Yellow River silt ecological resources will be fully developed and released.关键词
