区域滑坡风险评估应该建立在可靠的前期基础工作之上,而滑坡风险区划和滑坡概率分析是滑坡风险评估的主要技术支撑,相互之间具有层次链的关系。通过滑坡风险的类型研究介绍了三者之间的关联性。根据研究的理论方法,选择三峡库区万州区进行实例应用,说明滑坡风险区划和滑坡概率对滑坡风险评估的贡献作用。在此基础上,进行了滑坡风险分布、滑坡风险概率、滑坡风险损失综合评估,构成了较完整的滑坡风险评估体系。
Landslide risk assessment should be based on reliable early foundation work, and landslide risk zoning and landslide probability analysis are the main technical support for landslide risk assessment, with a hierarchical chain relationship between each other. According to the type of landslide risk, the correlation between the three is introduced. According to the theoretical method of the study, the Wanzhou District in the Three Gorges Reservoir Area is chosen as an example to illustrate the contribution of landslide risk zoning and landslide probability to landslide risk assessment. On this basis, landslide risk distribution, probability of landslide risk and landslide risk loss comprehensive assessment, constitutes a more complete landslide risk assessment system.
