安徽南部黟县地质灾害特点及变形破坏模式
|
摘要
研究地质灾害特点及变形破坏模式是地质灾害防治的基础,具有重要的指导意义。本文基于安徽省南部黟县大量实地调查成果资料,从地形地貌、地层岩性、构造、水文特征等方面归纳总结了黟县地质灾害特点。研究结果表明,黟县地质灾害点多面广、规模小、发生频率高,沿溪沟和交通沿线分布,地质灾害类型与斜坡坡度、高度、和形态相关,地层岩性、结构、风化、节理裂隙等控制了地质灾害的类型及力学机制,降水对岩土体的软化、润滑、侵蚀作用是这些灾害的诱发因素。在深入分析基础上,建立了黟县地质灾害变形破坏的模式。
Research of characteristics of geological hazards characteristics and their deformation-failure models is vital for disaster prevention.The objective of this paper is to analyze the features of geohazards in Yixian County,southern Anhui Province.Our work is based on a number of field investigations,involving topography,landforms,strata,litholgy,structure,and hydrology.The results show that the geological hazards in this region are characterized by wide distribution,small scales,and high frequency,mostly along creeks and traffic lines.The types of the hazards depend on the angle,height,and shape of hill-slopes.Lithology,structure,weathering,joints and fissures control the types of geological disasters and mechanisms.Softening,lubrication,and erosion on rock and soil by precipitation can trigger these geo-hazards.Based on in-depth analysis,this work established deformationfailure models for geo-hazards in this area.
