西安长安区南郊原状黄土边坡稳定性研究与分析
Study and Analysis on the Stability of Undisturbed Loess Slope in the Southern Suburb of Chang’an District, Xi’an

随着降雨量不断北移，导致西北地区边坡稳定性降低。本文对西安长安区原状黄土进行地勘取样并进行室内三轴压缩试验，获得土样抗剪强度c、φ值，结合工程实际案例建立模型，利用Abaqus软件的强度折减法验证边坡稳定性系数。对西北地区边坡稳定性分析以及防护措施有着重要意义。
With the continuous northward movement of rainfall, slope stability decreases in northwest China. In this paper, geological prospecting and sampling of undisturbed loess in Chang’an District of Xi’an were carried out and indoor triaxial compression tests were conducted to obtain the c and φ values of the shear strength of the soil samples. A model was established based on practical engineering cases, and the strength reduction method of Abaqus software was used to verify the stability coefficient of the slope. It is of great significance for slope stability analysis and protection measures in northwest China.
