Abstract：
Using the Numerical calculation software FLAC3D, this paper carried out the comparative study between the supporting form mechanisms of prestressed anchor composite soil nailing and soil nailing. The main target is to study the differences between them in limiting slope displacement and supporting structure forces. It preliminarily discussed the questions of the failure mechanism in the prestressed anchor composite soil nailing supporting form, the synergistic mechanism between the prestressed anchor and soil nailing. This paper could form the theoretical basis for the optimized design of composite soil nailing structure.
