EFFECT OF SUB-SOIL STRATIFICATLON ON UPLIFT PRESSURES BELOW HYDRAULIC STRUCTURES

Abstract

' he paper embodies the r. cults of experimental as well. as r icai studies on peiential flow of water through mUiti-» la red x soils having diffezent permeabilites, underlying U) a simple floor and (ii) a depressed floor. Studies for the experimental. 2atermination of uplift pressures below founds tons have been carried out by Electrical alogy tecbniq *c and by ..c* 'ield Plotter,& ralyt1ca1 iork has been done by the method of .claztin fo finite d1ffernce solutions and b $chww-z'z C istotfel Tr cforntion for exact soiutic ns.
