Triaxial Permeability Device

Abstract

The triaxial permeability device can be used to evaluate the hydraulic and chemical conductivities of compacted fine grained soils. This device provides control of the primary variables affecting hydraulic and chemical conductivity; void ratio, soil structure, stress history, state of stress, drainage conditions, properties of the permeate, degree of saturation, thixotropy, and gradient. Methodology for evaluation of conductivity for fine grained soils using water and/or chemical permeants is discussed. The design of the permeability apparatus is discussed in detail followed by descriptions of the procedures used to prepare and consolidate specimens, monitor the equilibrium hydraulic conductivity, change permeants, and interpret the data. A limited amount of initial test data is presented and discussed, along with recommendations for continued study. Theses. (jhd)
