本文研究了无定形硅、铁、铝对土的力学性质和微观结构的影响。研究结果表明,无定形物质能加强土颗粒间的连结和结构强度,含无定形物质的士通常含水量高,孔隙比大,周围环境的物理化学因素变化时,其力学性质也容易变化。 In this paper, the effects of amorphous silicon, iron and aluminum on the mechanical properties and microstructure of soil were studied. The results show that the amorphous materials can enhance the bonding and structural strength between soil particles. The amorphous matter-containing taxis usually have high water content, large void ratio and changes in the physical and chemical factors of the surrounding environment, and their mechanical properties also easily change.
