Bearing Capacity Analysis And Design Of Highway Base Materials Reinforced With Geofabrics, Tommy C. Hopkins, Liecheng Sun, Mikhail E. Slepak

Kentucky Transportation Center Research Report

The primary objective of this study was to develop and implement mathematical bearing capacity models originally proposed by Hopkins (1988, 1991) and Slepak and Hopkins (1993; 1995). These advanced models, which are based on limit equilibrium and are operated together, can be used to analyze the bearing capacity, or stability, of early construction of loads on a single layer of material, two-layered problems involving a layer of base aggregate and subgrade, and a foundation involving multiple layers of different materials, such as a flexible asphalt pavement. A Prandlt-type shear surface is used in the model analyses of layered foundations. In …
