运用从延安新区工程建设现场取得的Q3原状黄土，开展了控制不同含水量的高压固结实验，得到了其压缩系数、压缩指数与压缩模量，并分析了Q3黄土的变形特性参数与上部垂直压力和含水率的关系，结果表明：压缩系数与压缩指数都随着含水量的增大而增大，当土体受到的垂直压力与含水率比较大时，压缩模量有先增大后减小的趋势。

The paper adopts the Q3 undisturbed loess from the construction site of Yan’ an New Region project, undertakes the high-pressure con-solidation tests by controlling different water contents, concludes its coefficient of compressibility, compression exponent, and modulus of com-pression, analyzes the relationship between the deformation feature parameter of Q3 loess and upper vertical pressure and water contents, and proves by the result that coefficient of compressibility, compression exponent are enlarged with increasing water contents and the modulus of com-pression has the tendency of the reduction followed by the increase when having larger vertical pressure and water content of the soil body.
