摘要: 利用轴平移法量测吸力技术,进行了等吸力三轴剪切试验,研究人工制备结构性黄土吸力与周围压力的关系;利用土吸力量测仪进行了原状结构性黄土吸力的量测,研究了结构性黄土吸力随含水量及饱和度的变化关系,随着三轴剪切试验的周围压力的增大,吸力逐渐减小;原状结构性黄土的含水量(饱和度)对吸力有显著的影响,随着土的含水量的增加吸力减小。

Abstract: The triaxial shear test in a constant suction is conducted using whole translation method. The relation between mad-made structural loess suction and confining pressure is studied. The undisturbed loess suction is measured using a soil suction measuring apparatus. The structural loess suction is studied when the moisture content and saturation degree change. The test shows the suction decreases gradually when the confining pressure of the triaxial shear increases and, the moisture content of undisturbed loess apparently influences the suction, the suction is decreased along with the increasing of loess moisture content.
