The influence of compress character of acid pollution laterite are examined by soak, considering concentration of acid solution, environment temperature, soaking time, dry density, preparation of acid pollution laterite, to carry out compress character test, in view of Yunnan typical laterite. The results show that, Soaked in acid laterite soil after compression performance than before immersion changed significantly. With the increasing concentration of the acid solution, immersion, soil porosity ratio increased, compression coefficient increases, and compression modulus gradually decreases; with the extension of immersion time, soil void ratio first increases and then decreases and finally increases to stabilize, compression coefficientfirst increases and then decreases and finally increases to stabilize, compressive modulus is eventually reduced to stable; with soaking temperature gradually rises, soil void ratio increases, compression coefficient increases, compression modulus decreases.%针对云南的典型红土，使用浸泡的方法，综合选择酸液浓度、环境温度、浸泡时间以及干密度的影响，制备酸污染红土试样，开展酸污染红土的压缩试验，研究浸泡对红土的压缩特性的影响。试验结果表明：酸液浸泡红土后的土体压缩性能较浸泡前变化明显。随浸泡酸液浓度的增大，土体孔隙比逐渐增大，压缩系数逐渐增大，压缩模量逐渐减小；浸泡时间越长，孔隙比先增大再减小最后再增大至稳定，压缩系数亦先增大后减小再增大至最终稳定，压缩模量最终呈减小至稳定；随浸泡温度的逐渐升高，土体孔隙比增大，压缩系数增大，压缩模量减小。
