Through the numerical calculation, this paper shows that soil nail and anchor rod internal force are "coefficient" shaped or parabola, and the maximum force of each row of soil nailing gradually shift towards the direction of the surface layer. With the increase of the depth of the excavation, soil nailing axial tension increases, and for the beginning of prestressed anchor free segment, along with the increase of the depth of the excavation, its axial force increases.The force of the end of the soil nail (anchor) is almost zero. Axial force and shear during excavation piles are gradually increased. The maximum shear pile move downward; the upper half part of the bending moment of pile is gradually increased. In the second half, under the range of 1m of the foundation pit, the moment value decreases the supporting structure of the internal force distribution.
