ENGINEERING PROPERTIES OF DREDGED SEDIMENT MODIFIED BY HAS STABILIZER
-
摘要: 为了探讨利用HAS土壤固化剂改性加固珠江河道疏浚淤泥的固化效果,进行了击实、无侧限抗压强度和抗渗等物理力学性能试验,通过对试验结果的分析,讨论了改性淤泥的压实性和抗压强度的变化规律。结果表明,HAS固化剂改性后,淤泥的压实和渗透性有很大的改善,同时淤泥的强度能得到较大的提高,建立了改性淤泥的强度与龄期、掺入比的关系式,可供实际工程参考。Abstract: In order to discuss the stabilization effect of useing HAS stabilizer to reinforce the Pearl River channel dredged sediments,the tests on the compaction,unconfined compressive strength and impermeability of stabilized sediment have been made.The results indicate that adding HAS stabilizer can improve the physico-mechanical performances of the dreged sediment.The compactibility, impermeability and strength are improve notably.A prediction equation is developed to calculate the strength of stabilized sediment by analyzing the experimental data.It can be used for reference in engineering practice.
