excavated rock slope meaning in Chinese

挖方岩石边坡

In this article , idealized elastic plastic model and three - dimension finite elements programs have applied to analyzing and researching the stress and displacement distribution of 4 high - steep slopes excavated on the wan - liang expressway , and the relationship has been gained between the stress existing in excavated rock slopes and stability coefficient with depth change through the self - made fortrain program ' s application to the computation of slopes " stability coefficient ; at the same time , through the analysis of the slopes " stability coefficient , such conclusion has been gotten that cohesion in the slipping zone has important effect on slopes " stability and some proposals have been presented to improve the anti - shearing ability of the slipping body through enhancement of the cohesion in the slipping body
本文采用概化均质的理想弹塑性模型，利用三维有限元程序分析了万梁高速公路4个高陡边坡开挖各阶段的应力及应变分布，并且编写了fortran程序用于边坡稳定系数的计算，得出边坡岩体应力及稳定系数随着开挖深度的变化关系。并对边坡稳定系数的敏感性进行了分析，得出滑带内聚力的变化对边坡稳定性至关重要，提出了改善滑带岩土粘结状态提高抗剪能力的工程措施。
