摘要
对高淳膨胀土进行了改良后的干湿循环试验研究,包括直剪试验和无荷膨胀率试验,研究了干湿循环对改良膨胀土抗剪强度和变形的影响。结果表明,随着循环次数的增加,抗剪强度逐渐减小,土的粘聚力c也逐渐减小;无荷膨胀率增大后趋于稳定。
This paper made the modified drying and wetting cycle test to Gaochun expansive soil,including the direct shear test and no-load expansive soil test,researched the influence of wetting and drying cycle to the shear strength and deformation of modified soil and expansive soil.The results showed that with the increase of number of cycles,the shear strength decreases,and the cohesive force c of soil decreased gradually,and the no load expansion rate increased steadily.
