摘要: 利用压力板对不同初始含水率与不同渗水方向的原状非饱和Q3黄土进行脱湿试验,分析不同初始含水率与不同渗水方向对原状非饱和Q3黄土土水特征的影响。研究表明:在相同的初始含水率情况下,基质吸力对土样不同方向渗水情况的影响基本相同;在渗水方向相同的情况下,随着基质吸力的增大,体积含水量逐渐降低,基质吸力增大到一定程度后,不同初始含水率对土水特征曲线的影响几乎一样。

Abstract: The desorption process experimental research on undisturbed unsaturated loess Q3 with different initial water contents and different seepage directions was conducted by using the pressure plate extractor, and the effects of them on the soilwater characteristics were analyzed. The test results show that under the condition of the same initial water content, the influences of the matrix suction on different water seepage directions are almost the same; under the condition of the same seepage direction, volume water contents gradually reduce with the increase of matrix suction; when matrix suction increases to a certain degree, the influences of different initial water contents on soilwater characteristic curves are nearly the same.

Key words: geotechnical engineering, undisturbed unsaturated loess, matrix suction, soilwater characteristic curve, water content
