【摘要】 为了对边坡稳定性做出客观合理的判断,将理想点法应用于边坡稳定性评价中,选取岩石质量指标、岩石结构特征、地应力等7个具有代表性的影响因子作为边坡稳定性评价指标体系;采用改进的熵权法确定各指标权重系数,建立了边坡滑移失稳的熵权-理想点法预警模型。结果表明:改进的熵权法与边坡实际稳定级别基本一致,验证了该方法的可行性和可靠性,证明此方法具有良好的工程应用前景。更多还原

【Abstract】 In order to make objective and reasonable judgment on slope stability,the ideal point method was applied to slope stability evaluation,and seven representative influencing factors such as rock quality index,rock structure characteristic and ground stress were selected to build the index system.The weight coefficient of each index was determined by the improved entropy weight method,and the early warning model of slope slip instability was established based on the entropy weight and ideal point method.The results show that the improved entropy weight method is consistent with the actual stability level of the slope,and the feasibility and reliability of the method are verified.It is proved that this method has a good prospect of engineering application.更多还原
