The applied stress versus surface settlement (SVS ) behavior from in-situ plate load tests ( PLT s) is valuable information that can be used for the reliable design of shallow foundations. In-situ PLT s are commonly conducted on the soils that are typically in a state of unsaturated condition. However, in most cases, the influence of matric suction is not taken into account while interpreting the SVS behavior of in-situ PLT s. In addition, the sizes of plates used for load tests are generally smaller in comparison to real sizes of footings used in practice. Hence, in-situ PLT results should be interpreted taking account of not only matric suction but also the scale effects. In the present study, discussions associated with the uncertainties in interpreting the SVS behavior of PLT s taking account of matric suction and scale effect are detailed and discussed.
