摘要

针对有机质对疏浚淤泥固化处理效果产生的影响，研究有机质的主要成分腐殖酸对水泥固化的影响。研究表明，腐殖酸对水泥的水化具有抑制作用，腐殖酸含量对淤泥固化土的无侧限抗压强度和破坏应变的影响存在一个极限含量（3.62 %），超过这一极限含量，随腐殖酸含量的增加固化土的强度和破坏应变几乎不再变化。同时，研究结果表明，随着腐殖酸含量的增加，固化土塑性增强。

Abstract

Organic matter often influences the effect of cement solidified soil

humic acid as the main composition of organic was chosen to study the effect on solidification. Test results show that humic acid hamper the hydration of cement

there exists a critical humic acid content of 3.62 %

when the humic acid content is higher than the critical value

continue increasing of organic matter content has little effect on unconfined compressive strength and failure strain

while the plasticity of solidified soil enhances with the humic acid content increases.
