VERTICAL STRESS FORMULAS FOR TRIANGULAR LOADING

For almost half a century, the exact mathematical solutions of the Boussinesq equation for a triangular load on a rectangular area have eluded investigators; therefore, approximate methods are being employed to calculate the vertical stresses at any point under the area. This paper introduces the exact equations derived by performing the required integration of the basic Boussinesq equation for a point load as applied to a rectangular area loaded with a triangular load. The vertical stress under the zero load corner and that under the q load corner are derived using the principle of superposition and the formulas for uniform surface load first developed by W. Steinbrenner. The total vertical stress and hence the average vertical stress for a soil of thickness h is also derived for use in settlement calculations.
