浅谈地质灾害隐患点辨识及数值模拟分析——以北京山区典型区域为例

Study on Identification and Numerical Simulation Analysis for Potential Geological Hazards——Taking Beijing Typical Mountainous Area as an Example

以北京山区典型区域为例,综合考虑地形地貌、地质构造、岩性特征以及水文地质条件等影响因素,对该区域潜在地质灾害的位置和类型进行了辨识,并采用数值模拟分析的方法,对辨识出的地质灾害发生情况进行数值模拟计算,通过计算结果验证对潜在地质灾害的位置和类型辨识的正确性,进而为后续建立地质灾害风险点地质模型,进行地质灾害风险点监测分析、提出预警信息奠定了基础,也为相似区域开展地质灾害类型的辨识及数值模型分析提供了参考价值。

In this paper,based on comprehensive consideration of topography,landforms,geological structure,lithologic feature and hydrogeological condition etc.,the location and types of potential geological hazards are identified in Beijing typical mountainous area,and the method of numerical simulation analysis is used.The results can provide a basis for model establishment of geological hazard points,monitoring analysis,warning information for geological disaster risk evaluation.The paper is also a good reference value for the identification and numerical simulation analysis of geological hazard types in similar regions.
