露天开采会产生大量的人工边坡,为了更好的对人工边坡的安全性进行评估,基于随机介质理论,推导出了边坡开挖导致岩土体的移动和变形计算公式,提出了开挖边坡变形破坏判据及周边环境安全评价准则。针对土体移动和变形计算公式的不可积性,对其计算方法进行了研究,采用条分法获得了预测开挖边坡岩土体变形的半解析解。通过工程实例,能很好的预测开挖引起的边坡体的位移和变形,同时利用变形破坏判据可方便的对边坡的安全性进行评估,为人工边坡的工程处治措施设计提供参考。
In order to better evaluate the safety of artificial slope, a large number of artificial slopes are produced in opencast mining. Based on stochastic medium theory, a formula for calculating the movement and deformation of rock and soil caused by slope excavation is derived. Deformation and Failure Criterion of Excavating Slope and Criteria of Peripheral Environmental Safety Evaluation. Aiming at the iniquity of soil movement and deformation formula, the calculation method is studied, and the semi-analytical solution to predict the deformation of rock and soil mass about excavation slope is obtained by the method of bar. Through the engineering example, the displacement and deformation of the slope body caused by excavation can be predicted well, and the safety of the slope can be conveniently evaluated by using the criterion of deformation and failure so as to provide a reference for engineering measures of artificial slope. .
