| 摘 要： | 在现场勘察和研究排土场地质条件的基础上,采用基于弹塑性模型的有限元法,计算了排土场的应力和位移.把数值模拟和传统的边坡稳定分析方法结合起来,得出边坡的安全系数,对排土场边坡的发展趋势作出了预测.研究表明:排土场第一台阶边坡稳定性比较差,有滑动的可能性,为此提出了相应的加固措施,为排土场边坡稳定性评价提供了技术支持.

| Abstract: | Based on the investigation data available and research on the junkyard engineering geology conditions,the finite element method based on elastoplastic theory is adopted to calculate the junkyard stress field and displacement field.Numerical simulation and traditional analysis of slope stability are combined to get the slope stability factor the and forecast of developing trend of actuality junkyard slope is offered.The simulation study results show: the first stage slope of the junkyard is unstable and has the probability to slide.At last,some retrofit methods are put up to provide some technique support for junkyard slope stability. |
