THE EFFECTS OF CONVENTIONAL SOIL SAMPLING METHODS ON THE ENGINEERING PROPERTIES OF COHESIVE SOILS IN LOUISIANA. ENGINEERING BULLETIN NO. 117

A comprehensive literature study was performed, eighteen hundred samples from six sampling sites representing several typical geologic formations of Louisiana were obtained, and about 1700 field and 6500 laboratory tests were performed. Engineering properties of soils studied showed inherent variations. Both samples provided specimens with least amount of disturbance. Sampling with small diameter than wall tests caused serious disturbances. It was found that the stress-strain relationship of soils were affected by sample size, and long-term (15 days or longer) storage of samples caused measurable changes in their properties. X-ray analysis of samples showed internal discontinuities and disturbances caused by sampling and handling.
