ABSTRACT
There are frequently occurred geological disasters in the vast territory of China. Every year, landslides, debris flows, ground collapses and etc. bring enormous economic loss and casualties, especially the landslides. Landslides groups in southern highland area of Jingyang are investigated and analyzed. Characteristics of and reasons for the landslides were statistically analyzed. A case history of a large-scale landslide in loess in Dongfeng village of Gaozhuang town in Jingyang is studied. The loess is widely distributed in China and landslides in loess are very typical. It is of great importance for preventing landslide to study its strength deformation characteristics and the mechanism of its formation and movement by both theoretical and testing methods. Taking Gaozhuang town as the starting point, variations of the angle, height and volume of some previous occurred landslides were statistically analyzed along the southern highland area from east to west.
