Research Project Abstract
We conducted a variety of tests on soil sampled from the Latah Creek floodplain according to ASTM standards. We then performed a series of Unconfined Compressive Strength tests on the soil at varying water contents to study the change in strength and behavior of the soil as a function of moisture conditions. To evaluate all the changes from the increased water content for each test, we created stress/strain curves that allowed us to determine the yield strength and the ultimate strength for each test. Results showed a decrease in both ultimate strength and yield strength as a result of increased water content.
