The study was undertaken at the request of Mr. H. K. Martin of the Oglebay Norton Company to evaluate several proposed foundation designs from the point of view of safety from deleterious seepage or piping. Estimates of the uplift pressures and exit gradients based upon flow net analysis were made to establish the hydraulic stability of the structure.en-USReport
