Effect of underground stress transfer through artificial manipulation of particle size distribution

To maintain the stability of built structures, engineers employ various methods to increase ground strength. One such method is to exert mutual physical force upon a structure, thereby stabilizing it without external reinforcement. Typical examples include the stone mastic asphalt method and torsional structured stonework. By simulating a structural phenomenon, it is possible to increase the ground's strength simply by manipulating the distribution and spatial arrangement of soil particles; soil composed of two differently sized particles satisfying a specific ratio does not separate easily. The jamming of soil particles utilizes Plato's regular polyhedron model and assumes that soil particles are complete spheres. Larger soil particles are placed at each vertex of a regular polyhedron and smaller particles in the voids
