Correlation Analysis on Influencing Factors and Deformation Mechanism of the Zhoujia Landslide in Yalong River
摘要
Abstract
The Zhoujia landslide is situated in the upstream of the Kala Hydropower Station,exhibiting features of substantial deformation,evident signs of destruction,and a large volume.If the landslide were to become unstable,it could trigger disasters such as surges,river blockages,and reservoir sedimentation,posing a threat to the safety of both the dam during construction and its subsequent operation,as well as environmental safety.The lasso-Random Forest(lasso-RF)and Spearman correlation analysis are used in this paper.Utilizing monitoring data of the Zhoujia landslide,it conducts an analysis of the correlation between factors and investigates the mechanisms behind deformation and failure.The results indicate that the deformation of the Zhoujia Landslide is more correlated with rainfall than seismic factors,with rainfall being the primary influencing factor.Rainfall has a delayed impact on landslide deformation.The surface displacement in Zone B1 shows a strong correlation with deep-seated displacement,indicating a collective sliding characteristic of the landslide.Therefore,enhanced monitoring of various indicators in Zone B1 is necessary.关键词
