摘要
水帘洞煤矿工业场地黄土高边坡为老滑坡的后壁,在边坡的脚下有老滑坡体残留物。论文在分析边坡失稳因素的基础上,根据反算法、类比法、室内试验结果、结合地区实际经验确定计算参数。运用圆弧法(瑞典条分法和简化Bishop法)和有限单元法(采用MSC.marc软件)对边坡的天然状态和优化设计后的稳定性进行计算、模拟评价。结果表明,天然边坡处于不稳定状态,经优化设计后的边坡安全系数达到设计要求。
The loess high slope of the industrial park in Shuiliandong Mine is the back - wall of old sliding slope and there is old sliding slope residual body at the foot of the slope, Base on the analysis on the slope stability lost factors, the paper confirmed the calculation parameters with the reversed calculation method, the analogy method, in door test results and the combined local actual experiences. The arch method （Sweden strip classification method and simplified Bishop method） and the finite element method （ MSC. marc software） ware applied to calculate and simulated assess the stability of the slope in the natural conditions and after the optimized design. The results show that the slope in the natural conditions is in a unstable condition and the safety coefficients of the slope after the optimized design reached to the design requirements.
