中文摘要：

采用不同比例石灰、粉煤灰、水泥对玄武岩残积土进行改性处理的两种不同改性玄武岩残积土,对其进行崩解特性试验和干湿循环下抗压强度。结果表明：玄武岩残积土在很短的时间内崩解,改性土在经历24 h之后,仍无崩解现象;改性土在刚开始的7次干湿循环下抗压强度明显的增大,之后随着干湿循环次数的增加而降低,最终两种改性土的抗压强度有相等趋势;并得出与天然的玄武岩残积土相比,改性土具有很好的水稳性。这为玄武岩残积土地区环境对工程建设的影响提供数据参考。

英文摘要：

Using two different with different ratio of lime,fly ash,cement on the residual soil of basalt modification treatment,and under performance test and under cyclic wetting,measuring compressive strength of modified residual soil of basalt.The results show that：the residual soil of basalt disintegration in a very short period of time,the modified soil is no disintegration phenomenon after 24 h;The compressive strength of modified soil increased obviously in the 7 cycle at the beginning,after decrease with the increase of cycle number,and last the compressive strength of both has the same trend;And compared with the natural residual soil of basalt,the water stability of modified soil is very good.It provides reference data for the effects of basalt area environment for engineering construction.
