针对前期研究中提出的两种滑坡灾害受灾体易损性定量评估模型,以一个实际滑坡灾害为工程背景,描述了这两种易损性定量评估模型的实际应用步骤。结合实例,从概念、基本假设、适用情况等方面,对两种模型的异同进行比较和分析得出,两种模型均定量地反映了典型受灾体在滑坡作用下的脆弱性;其中一种模型从冲击过程量能转化的角度反映了受灾体具体的毁损程度,适用于需要精确计算破坏程度的情况;另一种模型则从概率的角度反映了受灾体破坏的可能性,适用于需要考虑滑坡致灾过程中不确定性影响,且只需考虑受灾体是否破坏的情况。从而为易损性评估模型的选取和应用提供了理论依据和参考实例。
In view of the two quantitative assessment models of vulnerability to landslide hazards proposed in the previous study, an actual landslide hazard is taken as the engineering background to describe the practical application of these two vulnerability assessment models. The comparison and analysis of the similarities and differences between the two models are made from the aspects of concept, basic assumptions and applicability. The two models all quantitatively reflect the vulnerability of typical disaster-affected lands under the landslide effect. One of the models From the perspective of the amount of impact process can be transformed reflect the specific damaged degree of disaster-affected body, suitable for the need to accurately calculate the extent of damage; the other model from the perspective of probability reflects the possibility of disaster-damaged body, suitable for landslides need to be considered Uncertainty in the process of disaster damage, and only need to consider the destruction of the affected area. This provides a theoretical basis and a reference example for the selection and application of the vulnerability assessment model.
