文章针对太佳高速公路某边坡黄土进行增湿固结排水三轴剪切试验,主要研究强度参数随含水量的变化规律,并基于强度折减法对含水量影响下的边坡进行稳定性分析,结果表明:黏聚力c随含水量的增大降低幅度较大,而内摩擦角φ随含水量增大降低幅度较小;随含水量的增大,安全系数降低,在低含水量阶段,降低幅度较大,随含水量增大,降低幅度变小。
In this paper, the triaxial shear tests of humidification consolidation drainage of loess on a slope of Taijia Expressway are mainly conducted to study the variation law of strength parameters with water content and to analyze the stability of slope under the influence of water content based on the strength reduction method The results show that the cohesion c decreases with the increase of water content, while the decrease of the internal friction angle φ decreases with the increase of water content. With the increase of water content, the safety factor decreases. In low water content stage, , A larger reduction, with the increase of water content, reduce the decrease.
