摘要
以成都某工程现场膨胀土样为研究对象,对不同干湿循环次数的膨胀土试样开展直剪试验,结果表明,在相同循环幅度和初始含水率下,随着干湿循环次数的增加,试样的抗剪强度不断减小,最终趋于一个稳定值。
A series of shear tests were conducted on expansive soil of a engineering site in Chengdu which was subjected to different drying-wettingcycles to study the influence of drying-wetting cycles on the strength characteristics of Chengdu expansive soils. The results show that as thenumber of drying-wetting cycles increases, the shear strength of expansive soil decay. Finally, itJ s going to end up with a stable value.
