以哈尔滨某施工工地取土场低液限粘性土为试验对象,通过室内直剪试验,得到了不同冻融循环次数对于6%掺灰的过湿石灰改良粘性土的抗剪强度的影响规律,试验结果表明:随着冻融次数的增加,过湿条件下石灰改良粘性土的抗剪强度降低,粘聚力减小、内摩擦角呈线性增加的变化趋势。

Taking the low liquid limit clay soil from a construction site field in Harbin as the test object. Through the indoor direct shear test,ob-tained the influence law of the different freezing and thawing cycles for 6% of the mixed ash wet lime improved on the cohesive soil’s shear strength. Experimental results show that with the increase of number of freezing and thawing,under the condition of wet,the lime improved cohe-sive soil’s shear strength is reduced,cohesive force decreases,internal friction angle of the change trend of linear increase.
