Experimental research on anti-freeze properties for the fiber reinforced solidified soil
摘要
Abstract
Based on the engineering properties of poor anti-freeze performance of the solidified soil and led to de-cline the engineering life,adopted the orthogonal experimental design method,has researched the quality loss rate and strength loss rate for the soil which blended polyester fiber and stabilizer after freeze-thaw cycle .The research obtained that:When the MBER soil stabilizer content was 9%,the quality loss rate after 10 cycles was more than 5%,when the stabilizer content wais 1 1%or higher,the quality loss rate after 20 cycles was less than 5%.But the fiber content had a small impact of the quality loss rate .When the stabilizer content was 13%and the fiber content was 0 .8 kg·m-3,the strength loss rate has reached 28 .5 1%which was the minimum .These results showed that:The stabilizer content had a large impact to the quality loss rate and strength loss rate,fiber content only had a certain impact to the intensity loss rate .关键词
