Geogrids provide reinforcement for aggregate materials through interlocking between granular particles and geogrid apertures. The reinforcement or stabilization effect of a geogrid can be quite different when used with similar aggregate types but having different particle size distributions. This paper describes recent research efforts at the University of Illinois focused on triaxial compressi...

To study the mechanical and energy evolution characteristics of sandstone under true triaxial cyclic loading, a test with different intermediate principal stress loading was conducted using rock disturbance unloading system. The influence axial load on deformation, evolution, macroscopic failure in systematically analyzed, damage law revealed. Results showed that mode compression changed from t...
