This work presents in collected form a non-linear stress-strain theory for soils. It relates the "principal stresses" and the "equivalent stresses" to the "natural overall strains" and considers volumetric changes and resistance under drained triaxial tests, and also void pressure and resistance under undrained triaxial tests. Deviatoric behaviour and secondary effects are not included. The complete theory is set out in terms of five constants which are independent of the type of triaxial test (compression or expansion, drained or undrained), of soil condition (normally consolidated or preconsolidated), and of level of stresses. The five constant parameters taken are: the angle of internal friction, phi; the coefficient of compressibility, gamma; the ratio between expansion and compressibility, rho; and the void pressure coefficients alpha and beta. For highly preconsolidated soils a sixth parameter is added for shear-strength, tau. The theory is illustrated by application to experimental findings. The work also includes a method for calculating settlements due to geotechnical structures or to change in the hydromechanical conditions (as a result of pumping for example), as well as correlations between some mechanical properties and those soil properties used as indices. /TRRL/
