不同冻融循环次数下加筋固化盐渍土的强度变化规律研究
Analysis of Mechanical Properties of Reinforced Solidified Saline Soil under Freeze-thaw Cycle
摘要
Abstract
Huanghua area is a seasonal frozen soil area,and soil salinization is serious,and frost heave and thaw settling problems often occur.The hardening tests of calcium carbide slag,fly ash and lcellulosic soil in this area were carried out to study the unconfined compressive strength(UCS)of the cured soil under different mix ratio and the variation of strength of the reinforced cured soil under different freeze-thaw cycles.The results showed that UCS increased first and then decreased with the increase of cementing material.The UCS of cured saline soil was the highest when the cementing material content was 30%and lignin content was 0.4%.With the increase of freeze-thaw cycles,the strength of reinforced solidified saline soil gradually decreased,and the residual strength was significantly higher than that of ordinary solidified soil,that is,the addition of lignocellulose could effectively improve the freeze-thaw resistance of saline soil.关键词
