ANALYTICAL AND EXPERIMENTAL EVALUATION OF MODULUS OF SOIL REACTION

The Iowa deflection formula has been the accepted design equation for flexible culverts for over 30 years. Unfortunately, design based on this formula is very sensitive to the modulus of soil reaction (E'). Because direct full-scale test measurements of this parameter have been scarce, researchers have attempted to supplement the data by several methods: finite element models and other elastic analyses, correlations with laboratory tests, use of test cells, rearrangement of the Iowa deflection formula, and monitoring of quantities simpler to measure (often with requisite assumptions). This paper investigates the drawbacks of some of these approaches.
