碱液法加固新近堆积黄土地基的研究

Study on Reinforcing Recently Piled Loess Ground with Alkaline Liquor Method

文章通过试验和工程实际资料,对碱液法加固新近堆积黄土效果、强度变化规律、附加沉降量大小,以及灌碱过程中单位土体耗碱量、单位土体耗液量及浓度的控制等灌碱技术进行了分析研究,提出了灌碱控制公式。同时对碱液法加固黄土质填土的适用性进行了探讨。

The efficiency of recently piled loess reinforced by alkaline liquor, the law of strength variation, amount of additional settlement, consumption of alkaline by unit soil mass during the pouring of alkaline, and the technigue to control the quantity and concentration of alkaline liquor are analyzed and studied herein through tests and practical engineering data. Controlling formula for pouring alkaline is proposed and the suitability of reinforcing loess fill with alkaline liquor. is explored.
