摘要： 为研究改良土的现状，得出改良土在不同化学作用、干湿循环等条件下物理和力学性质的变化规律,总结掺加不同比例的水泥、石灰、粉煤灰等改良土，得出这些条件下对改良土物理力学性质的影响；同时，研究了赤泥和不同掺料、赤泥改良土的物理力学性质的变化规律。赤泥作为工业废渣，改良土物理力学性质变化机理的后续研究，有十分重要的意义。

Abstract: To study the physical and engineering properties of the improved soil under different chemical additives and dry-wet cycles conditions, this paper summarizes the state-of-the-art research of improved soils. Soil sample with different amounts of cement, lime and fly ash are reviewed and the impact of these additives on the physical and mechanical properties of improved soils are investigated. At the same time, the physical and mechanical properties red mud with various amounts of additives are also investigated.

Key words: Improved Soil, Red Mud, Physical and Mechanical Properties, Modifications
