摘　　要：为全面利用滑坡地表布置的所有位移测点的数据信息、消除不同位移趋势分析评价方法对滑坡稳定性状态的误判,提出了一种融合多测点位移信息和多指标评价结果的滑坡稳定性状态模糊综合评价方法。实例验证结果表明,该方法避免了采用单一测点位移变化趋势对滑坡稳定性状态评价的不足,而考虑多种评价方法得到的评价结果也避免了单一评价方法对滑坡实际稳定状态评价的局限性,评价结果更加合理。In order to make full use of the data information of all the measuring points on the landslide surface and to eliminate the misjudgment of the landslide stability state due to different evaluation methods based on displacement trend analysis,a fuzzy comprehensive evaluation method for landslide stability state was proposed,integrating the displacement information from multiple measurement points and the evaluation results of multiple indices.The validation results from case studies show that this method avoids the shortcomings of evaluating landslide stability based on the displacement trend of a single measuring point.Additionally,by considering the results from multiple evaluation methods,it also avoids the limitations of using a single evaluation method for assessing the actual landslide stability state,making the evaluation results more reasonable.
