中国典型粘黄土区地质灾害风险评估危险性影响因素分析

地层岩性、岩土体结构及其工程地质特性为黄土区地质灾害提供了物质基础，黄土斜坡的坡型、坡度、坡高、阶地等地形地貌因素为地质灾害提供了边界条件，人类工程活动和降雨为黄土区地质灾害提供了触发条件。黄土地形地貌、地层岩性、岩土体结构类型及其工程地质特性、水文地质条件等为粘黄土区地质灾害形成的内在因素；降雨、人类工程活动等为其诱发因素。

An analysis of the danger influence factors of geohazard risk assessments in typical stick loess regions in China

Stratigraphy and lithology, rock and soil mass textures and their engineering geological features afford a material basis for geohazards in loess regions. The topographic and landform factors such as the pattern, gradient, height and terraces of loess slopes are the boundary conditions for geohazards. Human activity and raining are the triggered factors to induce geological hazards. Human engineering activities and precipitation provide the triggering conditions of geohazards in loess regions. The topography and landforms of loess, stratigraphy and lithology, rock and soil textures and their engineering geological features and hydrogeological conditions are the internal factors for the formation of geological hazards in stick loess regions, and precipitation and human activities are the inducing factors.
