The utility model provides a soft rock tunnel portal side slope reinforcing structure which comprises a tunnel body, a portal upward slope and road side slopes located on the two sides of a road, the portal upward slope and the road side slopes are each composed of a plurality of slopes and a plurality of flat slopes in a staggered mode and are of a stepped structure, and a plurality of frame grids are arranged on each slope in rows. A planting area is arranged in the middle of each lattice, a drainage channel is arranged at the slope toe of the road side slope, and the hole upward slope and the road side slope are arranged to be in a step shape so that accumulated water on the slope surfaces can be guided and buffered, in other words, the flowing speed of water is slowed down while drainage is conducted, and scouring of water flow to the slope body and the slope toe is reduced. Meanwhile, soil and rocks falling on the slope surface are buffered, potential safety hazards are reduced, a certain soil fixing eff
