The book presents a set of issues or problems of mechanics soil and landslides. Use different mathematical and physical models to calculate the motion of landslides. The book is based on the generalization of advanced technical solutions in the field of structural mechanics unstable soils and accompanied with numerical examples. In the book are examples of calculation of technical reinforcing structures landslides that facilitate the development of complex computational methods. The book is a wide range of master's degrees, graduate students and professionals - engineers and designers involved in the mechanics of landslides.
