摘 要: 在研究单一离子对水泥加固土强度影响的基础上,通过正交试验研究Mg2+,Cl-,SO2-4 3种离子共存时水泥品种及其外加剂对水泥加固高含盐软土性质的影响及其特性,并对水泥固化土中的固化剂和添加剂的适应性进行探讨,该试验成果对探索水泥加固高含盐软土改良技术的研究具有一定的理论和指导意义。
关 键 词: 地基基础工程;软土;水泥;添加剂;无侧限抗压强度

Abstract: Based on the research results of effect of single ion on the salt-rich soft soil improved by cement, the combined effect of additives on the characters of the salt-rich soft soil with Mg2+, Cl-, SO2-4 improved by cement was researched through the orthogonal tests of multiple ions, and the feasibility of curing agent and additive to improving the strength of the salt-rich soft soil improved by cement was explored as well. The research results have the good references for exploring the feasible technology of improving the characteristics of the salt-rich soft soil improved by cement.
