建立了边坡岩体稳定性分级模糊多层次综合评价的方法,考虑诸多影响边坡岩体稳定的因素,根据以往经验采用了半梯形和三角形函数建立单因素隶属函数关系式,提出了定性评判因素隶属函数的建立方法,利用层次分析法及专家工程经验确定了权值;在算子的选择方面,同时采用四种算子对边坡稳定性进行综合评判;针对不同工程边坡所考虑的因素种类和数量可能不同的情况,结合实例阐述了该数学模型的使用方法;最后将该方法应用于采矿、基坑和滑坡灾害的9个边坡的稳定性评价中,与实际边坡稳定性情况吻合,证明了该数学模型在边坡岩体分级中的适用性和准确性。
Based on the past experience, the semi-trapezoidal and triangular functions were used to establish the single-factor membership function, and the qualitative evaluation was put forward The membership function was established based on analytic hierarchy process (AHP) and expert engineering experience. In the aspect of operator selection, four kinds of operators were used to evaluate the stability of slope at the same time. According to the consideration of different engineering slopes Finally, the method is applied to the stability evaluation of 9 slopes of mining, foundation pit and landslide disaster, and compared with the actual slope stability The results are consistent with each other, which proves the applicability and accuracy of the mathematical model in slope rock mass grading.
