摘要
由于特殊的成土环境、颗粒级配及矿物成分等,黄土结构疏松,孔隙度高,导致其工程地质特性不佳。对黄土进行改性处理,可使其力学特性及工程地质特性得到明显改善,达到黄土区工程建设所需的承载力水平。利用固结剂对黄土进行改性,可以节省大量的人力和物力,效果良好,是目前国内外研究的热点之一。工农业废弃物产生量大,可以用作黄土的固结剂。因此,有必要结合土壤固结剂的种类,综述基于工农业废弃物的土壤固结研究现状,以更好地消纳工农业废弃物,改善土壤性质。
Due to the special soil environment,particle size distribution,and mineral composition,loess has a loose structure and high porosity,resulting in poor engineering geological characteristics.Modifying loess can significantly improve its mechanical and engineering geological properties,reaching the required bearing capacity level for engineering construction in loess areas.The use of consolidation agents to modify loess can save a lot of manpower and material resources,with good results,and is currently one of the hot research topics at home and abroad.Industrial and agricultural waste generates a large amount and can be used as a consolidating agent for loess.Therefore,it is necessary to combine the types of soil consolidation agents and summarize the current research status of soil consolidation based on industrial and agricultural waste,in order to better absorb industrial and agricultural waste and improve soil properties.
