Introduction

In order to standardize the design of landslide prevention and control, unify technical standards, and ensure that the basis is sufficient, safe and reliable, economically reasonable, and technically feasible, this book is specially formulated standard. This standard fully absorbs the Three Gorges Project Reservoir on the basis of domestic and foreign technical standards and more mature methods for landslide control design Landslides, Wenchuan earthquake disaster area and railway, highway, water conservancy and hydropower, urban construction and other landslide prevention and control design experience compilation. This standard uses advanced technology The operation method, fully combined with specific reality, strives for strong operability and is easy to implement in an all-round way. Code for design of landslide control

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Landslide The geological body slides downward along the weak geological surface under the action of gravity. Note. Landslides usually have a double meaning, referring to the process of gravity sliding, or the geological body and the accumulation body formed by gravity sliding. 3.2 Slip surface The interface between the sliding and accumulation of landslides, including the sliding surface formed during the sliding shearing process and the sliding process formed during the overlying accumulation process Cladding. ......
