1、It is shown that current landslide mass of Yanzipin is still active.
2、The loess landslide movement is a non stationary complex one combined with earth microtremors, the hydraulic gradient of high osmosis and strong shear force of landslide mass.
3、By analyzing the geological condition in the area of the potential landslide, the contributing factor of potential landslide mass is put forward and its stability is checked.
4、Therefore, the quality of dam material should be firstly analyzed, and the best alternative method is to replace the landslide mass with well-graded and high shear-strength earth materials.
