摘要
针对金坪子Ⅱ区蠕滑边坡体三维形态显著问题,为获得稳定性评价,基于地质勘察资料构建了三维计算模型,采用三维极限平衡法计算了各工况下的安全系数,分析了各指标对安全系数的影响程度,并提出采取降低地下水位方法以提高边坡的稳定性。结果表明,该方法有效、合理,与实际相吻合。
A three-dimensional calculation model,based on the geological survey,is established for obtaining an objective evaluation of stability,while the three-dimensional morphology of creep slope for Jin-Pingzi Area II is significant.The safety factor of each condition is calculated by using three-dimensional limit equilibrium method.And then the power degree of safety factor influenced by each index is analyzed.Finally,the method of reducing the underground water level is proposed to improve the stability of slope.The results show that the proposed method is effective and reasonable;the result is accord with the actual situation.
