摘　　要：为了探索夯实水泥土桩在黄土地区的适宜性及可靠性,通过压缩试验分析了不同影响因素对夯实水泥黄土压缩性的影响。研究表明:夯实水泥黄土的压缩性较原状黄土大大降低;夯实水泥黄土的压缩系数随着初始含水量的增大先降低后增大,在最优含水量附近达到最小值;压缩系数随着掺入比和夯实功的增大均呈减小的趋势。In order to explore the suitability and the reliability of compacted soil-cement pile in loess districts,influence of different factors on compressibility of compacted cement-loess were analyzed through compression test.The results showed that the compressibility of compacted cement-loess reduced greatly contrasted with intact loess.Compressibility coefficient of compacted cement-loess first decreased then increased as initial water content increased and a minimum existed nearby optimum moisture content.Compressibility coefficient had a tendency of reducing as cement mixing ratio and compactive effort rose.
