摘要

天津滨海新区广泛分布的海积软土很难直接满足工程建设需要。使用目前较为普遍的水泥系固化剂固化时，欲获得较高的强度必须提高固化剂的掺量。这样，势必增加工程造价。以水泥为主剂，同时掺入一定量的NaOH作为辅剂，对此种地基处理方法进行深层次理论探讨、微观结构分析以及现场验证试验。结果表明，水泥土掺适量的NaOH加固天津海积软土效果甚佳，值得在工程中推广使用。

Abstract

Much marine soft soil lying in Tianjin inshore area

which can not be used in engineering construction. When we commonly used cement solidification agent to consolidate soil with high water content to get high consolidation strength

we must improve the content of solidification agent

as a result the cost of engineering is higher. We use cement as main agent

and adding NaOH as assistant agent; at the same time give deeply theoretical probe and micro-structure analysis as well as verified test in foundation treatment; the results indicate that cemented soil adding NaOH has better effect on solidifying marine soft soil in Tianjin inshore area; so good to use widely.
