Abstract:

In the paper, 3 calculation methods of the combined retaining structure of soil nailing and pile-anchor are discussed， analysis was made on each advantages and disadvantages. 3 methods were taken for a specific assumptive engineering case， the calculation contrast indicated that the finite element numerical analysis is the closest to the actual, which can be applied to aided design.

Key words:soil nailing; pile-anchor; combined retaining structure; finite element
