摘 要: 针对2种淤泥土样,通过室内试验研究了有机质含量对水泥土强度的影响规律。结果表明:随有机质含量的增加,水泥土试块随龄期增长发生不同的形态变化,在加载过程中发生从脆性破坏向塑性破坏的转变,无侧限抗压强度随有机质含量的增加而降低,并提出了"有机质软化含量"的概念,对不同的土样其有机质的软化含量不同。 The influence of organic content on the strength of cement-stabilized soil was conducted through laboratory tests. Results indicate that: with the increase of organic content, cement-stabilized soil blocks has different forms in different ages, the destruction will change from brittle to ductility in the loading process, unconfined compressive strength decreases with organic content increase, and there iss a softening organic content that is different with different soil.
