Characterization of the Shear Strength of Unsaturated Soils and the Role of Soil Moisture Characteristic Curves

摘要

This is a two-part research program that focuses on the fundamentals of unsaturated soil mechanics. The funding agreement was for three years with one no cost extension. This report is the final project report. The aim of the first part was to modify the MIT method to measure rapid and continuous soil moisture characteristic curves under drying conditions so that the wetting curve can also be obtained with computer.
