Under the combined influence of the lateral restraint effect of the filler and the upward conflict effect of the sidewall of the cell on the filler, the geocell forms a composite body with greater compressive strength, shear strength and flexural rigidity. The effect of the geocell reinforced structure is mainly to disperse the foundation load on a larger area of the underlying layer, thereby reducing the load strength, lowering the shear stress level of the structure, and increasing the modulus and strength of the soil. Significantly reduce the horizontal and vertical displacement of the soil.
Compared with the geogrid, the advantages of geocell reinforced soil are:
1. When paving reinforcement, the reinforcement is only the reinforcement itself; for geocell reinforcement, the reinforcement has become a composite body composed of the cell and the filler;
2. The tensile function of tile reinforcement is exerted through the conflict of the soil reinforcement interface; and the cell reinforcement is exerted by directly controlling the lateral expansion of the filler, so the tensile function of the reinforcement can be used more;
3. For the geocell, the soil-reinforced conflict coefficient is the internal conflict coefficient of the filler itself, so it can provide much greater adhesion strength than the flat reinforcement. The effect mechanism of the geocell in dealing with uneven settlement of the subgrade is: because the geocell provides a greater lateral restraint effect on the filler, the sidewall of the cell produces an upward conflicting support force on the filler, and then forms a large A composite body of flexural and tensile stiffness and shear strength.
