【摘要】 以山西省临离高速公路黄土路堑高边坡为例,通过分析导致黄土边坡失稳的影响因素,确定黄土边坡失稳的敏感性因素。根据双因素方差分析理论,利用岩土工程有限元软件PLAXIS,采用强度折减法进行边坡安全系数的计算,分析了粘聚力和内摩擦角对边坡稳定性和滑动面位置的影响。该研究成果为黄土地区边坡失稳的预测和防治提供了一定的参考。更多还原

【Abstract】 The cutting high slope at loess areas between Lin county and Lishi highway in Shanxi Province is taken as an example,and the sensitivity factor of loess slope is determined by analyzing the influential factor which may lead to the instability of loess slope.According to the two-factor variance analysis theory,by using finite element software PLAXIS in geotechnical engineering,the slope safety factor can be calculated through the strength reduction method,the effects on slope stability and the position of the slide plane are also analyzed due to soil cohesion and internal friction angle.The results can be served as a reference in predicting and preventing the instability at loess areas.更多还原
