Fracture in Stabilized Soils. Volume 1.

Abstract

Conventionally the thickness design of stabilized soil layers has been based upon the tensile strength of the stabilized soil layer and/or the appearance of the first crack. The design literature does not allow one to consider the true development of cracking in the stabilized soil layer. Knowledge of the mode of such crack could drastically alter the philosophy behind thickness design of layers. In this research the principles of theoretical fracture mechanics are used to explain the mode and mechanism of fracture in fine grained media stabilized with portland cement. Experimental fracture mechanics is used to validate or verify and in some cases to investigate more fully the hypothesized mechanisms of fracture. The influence of osmotic and matrix soil section, temperature, binder content, thermal and kinetic energy, from sources outside the crack, are considered in the study. Linear elastic fracture mechanics is proven to be a highly acceptable analytical tool for these materials. Keywords: Fracture mechanics; Stress analysis; Strain mechanics.
