Th anti-side pile engineering design for reservoir landslide is a topic of general interest in engineering domain. It is quite important how to determine rationally design landslide push-force to optimizing design of anti-slide pile. Based on studying thoroughly pushing force curve

aiming at the question existing in "specification" and engineering design

the concept of " fundamental calculation cases" and " control and design calculation cases" are proposed. For down-slide section and slide-resistant section of the landslide

different determining method of design push-force is provided. All these are applied to engineering design of Songjiawuchang landslide; and the enormous economic benefits will be produced.
