Plate-Load Tests on an Unsaturated Lean Clay
Summary Plate-load tests are a common field method to estimate soil bearing pressure. Classic-result-test interpretations do not consider the matric suction effect. This paper analyzes the matric suction effect in bearing pressure from plate-load tests conducted in a lean clay soil. Seven plate-load tests were carried on in an unsaturated lean clay deposit; two of them were performed in saturated condition to verify the site homogeneity and test repeatability, five of them took into account different matric-suction values. Matric suction along the plate influence zone was monitored with four Jet Fill tensiometers, inserted at 0.1, 0.3, 0.6 and 0.9 m around every test pit. The results show bearing pressure values are highly influenced by matric suction changes.
