摘　　要：以重庆地区的素土和稻草秸秆为原料，按照不同的秸秆掺加量制作出不同配比的生土试件，对其进行单轴压缩试验及改性生土的强度和变形测试，发现掺加适量的稻草秸秆可提高抗压承载力和延性，根据数据对比分析，提出掺加稻草秸秆的最佳比例范围0．25％～0．5％。Taken plain soil and rice straw in Chongqing area as raw materials, raw soil test pieces of different combination were prepared by adding different amount of straw. Then, uniaxial compression experiments were conducted, and strength and deformation tests were conducted on the modified raw soil. It is found that by adding an appropriate amount of straw stalk, compressive strength and ductility can be improved. According to the data comparative analysis, the paper puts forward that the best proportion range of adding straw stalk is from 0.25%-0.5%.
