由于影响近坝库岸稳定性的因素很多,部分影响因素难以量化,且各因素之间的关系往往为非线性,很难用数学、力学方法进行准确地描述和求解。以某水电站近坝库岸为例,将层次分析法和二级模糊评判相结合用于评价库岸的稳定性。结果表明,该水库近坝1.79km不稳定岸坡主要集中于左岸,且上下游段岸坡较不稳定,中部段岸坡较稳定,稳定性好、较好、较差区域分别占总区域的50%、30.76%、19.24%,评价结果与实际情况较接近。 Because of the many factors affecting the stability of bank near the bank, some of the influencing factors are difficult to quantify, and the relationship between the factors is often non-linear, it is difficult to use mathematical and mechanical methods to accurately describe and solve. Taking a reservoir near dam bank as an example, the analytic hierarchy process and the second-level fuzzy evaluation are used to evaluate the stability of the bank. The results show that the unstable bank slope of 1.79km near the dam mainly concentrates on the left bank, and the bank slopes of the upstream and downstream sections are not stable. The bank slope of the middle section is stable and has good stability, which accounts for 50% and 30.76% of the total area respectively %, 19.24%, the evaluation results are close to the actual situation.
