Stability Analysis of Sanzhangtian Landslide in Yunnan

论文摘要

This paper determines the geographical location and geological structure of the landslide area based on comprehensive technical means such as on-site investigation and laboratory tests.By using various means including drilling and shallow well trenching,the lithology of the study area,the position of the sliding surface,the rock mass composition of the sliding zone,and the structure of the sliding body are examined.The results show that:（1） Sanzhangtian landslide has undergone multiple deformations such as tensile failure in recent years.（2） The unstable sliding surface of the landslide is located at the soil-rock joint surface,and the lithology is silty clay.（3） The rock and soil body at the contact surface of the landslide and the bedrock is located below the groundwater level in the study area.Sliding will occur due to the impact of groundwater and continuous rainfall.（4） According to the Sanzhangtian landslide drilling,the shallow well trenching combined with the main section of the landslide sliding along the main axis,it shows that there are two possible landslide shearing locations in the study area.The 1# shear crack is located in the middle of the landslide,the basketball court of Xinwen Primary School;the 2# shear crack is located on the slope corner or the bank of the dry river.（5） Based on the quantitative study of landslide body stability,the sliding body is basically stable-under-stable.
