Abstract: The paper considers a situation of the landslide area at An Khe Pass along highway 19, Dinh province and analyzes the causes and factors triggering instability. Laboratory testing and Limit Equilirium method (LEM) are two essential methods used. Initial results indicate that this area includes many sensitively unstable locations along An Khe Pass, particularly at an elevation from 400 to 600 m. The study also analyzed the mechanical properties of engineering geology, hydrology, geomorphology, weathering, and land use around sensitive areas. Results of model simulations demonstrated Lhat depending on the rainfall intensity in a rainy season, the surface flow eroded material strongly and caused liquefaction quickly leading the loss of balance on slopes, causing critical roads no active and paralysis. Therefore, the output of research is a fundamentalist to evaluate the impacts of geodynamic processes and to propose appropriated solutions for prevention.
