Testing study on the strength and deformation characteristics of soil in loess landslides

摘要

Landslides groups in southern highland area of Jingyang are investigated and analyzed. Char-acteristics of and reasons for the landslides were statistically analyzed. A case history of a large-scale landslidein loess in Dongfeng village of Gaozhuang town in Jingyang is studied. The displacement,maximum width,circumference and volume of the slipping mass were obtained through in situ measurement. Laboratory testswere carried out on soil samples taken from a depth of 2 m below the front edge of the slipping mass. Basicproperty and shear strength parameters of the loess soil were obtained. These results will benefit further studieson the kinetic mechanism of loess landslide in southern highland area of Jingyang.
