摘 要: 以重庆市万州区典型滑坡为例,根据其特有的地质环境条件,选取滑坡发育高差、坡度、降水、人类活动等11项因素作为滑坡危险性评价指标,通过灰色关联分析得出影响因素权重的大小,以灰靶决策理论为基础,构建多因素加权灰靶滑坡危险性评价模型,根据所得靶心距的大小,对滑坡的危险性进行量化评价,将滑坡危险性划分为高度、较高、中度、低度和较低5级,对研究区域内6个重点滑坡体进行危险性评价,获得每个滑坡体的危险性等级,并与自适应模糊评价法、神经网络评价法和PSO-BP评价结果进行比较。研究结果表明:多因素加权灰靶决策模型科学合理,符合实际情况,为滑坡危险性评价提供一种新思路。

Abstract:Starting from the geological environmental conditions within Wanzhou district in Chongqing, the 11 influencing factors were selected, including elevation, slope, precipitation, human engineering activity and so on. Based on grey target decision theory, the weights for screened evaluation influencing factors were determined based on grey association analysis method, and then multi-index weighted grey target model about hazard susceptibility assessment of landslide was established. According to off-target distance, landslide risk classification standards are established, and then the landslide risk rating was divided into high, moderate and low. Based on weighting-grey target decision evaluation model, 6 landslides risks in study area were assessed and analyzed. Each landslide risk was obtained.Compared with evaluation results of adaptive euro-fuzzy inference system, ANN and PSO-BP algorithm, the evaluation results are consistent with actual situation and reasonable. Thus, the model can provide a new idea for landslide hazard evaluation.

 

Key words: landslide; risk assessment; grey target decision; off-target distance; weight
