| 摘 要： | 本文以某电厂铁路沿线边坡为研究对象,采用有限元法结合极限平衡法分析了边坡稳定性。通过有限元分析,给出了边坡岩体应力及应变分布,分析表明,边坡岩体加荷后未发现大剪应变的贯通区。刚体极限平衡法评价了沿节理滑动的边坡稳定性,三个剖面边坡稳定性系数均大于1.4。安全系数均符合相关规范要求,计算结果为边坡加固设计提供了重要依据。

| Abstract: | Based on the finite element method and limit equilibrium principle,the slope stability along railway beside electricity factory was analyzed in this paper.The stress and shear strain distribution in the slope rockmass were obtained through finite analysis.It was discovered that there was no large shear deformations by construction loading.Three safety factors(Fs) were all higher than 1.4 in the three slope sections sliding along joint planes by limit equilibrium evaluation,satisying the specific requirement... |
