摘要
以陇南市礼县烂山滑坡为研究对象,在调查分析研究区地质环境条件的基础上,采用区域测量、地面调查和地下勘探等手段,详细研究滑坡的特征,分析滑坡的成因,准确地选取和确定了烂山滑坡滑体土的抗剪强度指标;运用定性分析和定量计算评价相结合的方法,综合分析评价了烂山滑坡的稳定性,为烂山滑坡灾害的治理工程设计提供了科学合理的设计参数和地质依据。
LanShan landslide in Li County served as the object of this study.Through an investigation and analysis of the geological conditions of the study area,using the area measurement,ground survey and underground exploration means,the characteristics of landslide were studied in detail and the origin of landslide were analysed.Then the shear strength parameters of the sliding zone soils were accurately selected and ensured.The method of qualitative analysis and quantitative calculation were used to comprehensively analyze and evaluate the stability of the landslide.This would provide parameters and a geological reasonable basis for LanShan landslide controlling engineering design.
