摘要
在室内实验条件下,向氯盐盐渍土中掺加不同含量、不同类别的盐类,通过实验研究土体抗剪强度参数的变化,分析了含盐量和含盐类别影响盐渍土抗剪强度的机理。研究表明:当土体含水量一定且含盐量达到9.36%时抗剪强度参数出现极小值。
Salt-bearing-soil can be treated as special engineering materials for containing soluble salt, which is changeable in state, so soluble salt can affect shearing strength parameters of salt-bearing-soil. The authors conducted the experiment in the laboratory to study the changes of Chlorine-salt-bearing salt shearing strength parameters with salt content and salt sort. The results show that the minimum of shearing strength parameters appears when water content is fixed and the total salt reaches 9.36%. In this paper, The authors analyze the mechanism of shearing strength of salt-bearing-soil, which is influenced by salt content and salt sort.
