摘　　要：通过对干湿灰土试样的室内三轴试验,分析养护龄期、含水率、围压以及干湿两种不同状态等因素对灰土应力应变曲线的影响。试验结果表明:灰土的养护龄期达到90 d后其强度增量逐渐减小;配制灰土的含水率宜小于最优含水率;浸水后灰土的强度降低20%～30%,而降低程度随围压增加而有所减少。Based on indoor triaxial test of lime-soil, the influence of stress-strain curve was analyzed which include curing period, moisture content, confining pressure and wet-dry two different state. The test result showed that the lime- soil after 90 days, the strength growth became slow. The moisture content of course should be optimum water content. The strength decreases about 20% - 30% after immersed. With the decrease of confining pressure,the strength of sample which was immersed reduced.
