The utility model discloses a side slope adds muscle structure, include along height of side slope direction level in proper order and lay a plurality of reinforcing layer in the side slope, each reinforcing layer edgewise the slope the slope in proper order backward the dislocation lay, reinforcing layer include the muscle material with lay the soil body in the muscle material, each reinforcing layer adopts the laying mode of different intervals in the side slope in the altitude range of difference, wherein the interval between each reinforcing layer between 16~12 at height of side slope will be less than the interval between each reinforcing layer in other altitude ranges of side slope. Through position and the interval that rationally sets up reinforcing layer, can effectively put forward high slope's stability, reduce domatic horizontal displacement, can save construction cost and cycle simultaneously.
