通过对西南地区千枚岩弃料压实土进行路用特性试验,可知千枚岩破碎结构块料在压实后颗粒级配变化中起主导作用;千枚岩混合料容易压实,但压实后具有高水平的遇水变形特性;千枚岩弃料是一种高分散性的土料,压实后遇水极易崩解。基于以上特性,在用千枚岩弃料作为路堤填方时要加以防范和进一步研究。
Through the test of the road properties of the diamined clayey soil in southwestern China, it can be seen that the crushed structure of the phyllite plays a leading role in the particle size distribution after compaction. The phyllite mixture is easy to compaction, but the pressure Possess a high level of water deformation characteristics; Phyllite abandonment is a highly dispersed material, compacted water easily collapsible. Based on the above characteristics, it is necessary to guard against further study when using phytoliths as embankment fillings.
