The physical model used for the various tests is a standard mini-pile installed in standard sand: Fontainebleau sand. This article explores the induced effects on the bearing shear capacity of the pile as a function of time, up to the point of failure, under different monotonic loads applied after periods of rest. A series of monotonic static loading tests, were performed on the pile. Tensile load tests, uplift, were performed before and after each series of static loads. A Lateral stress was observed at the start of the experiment at the pile-soil interface. It disappears as soon as the pile is driven into the soil, due to the dilatancy of the soil. This observed phenomenon is probably due to a decrease in non-mobilized lateral friction at the start of the experiment. A study of this phenomenon will be described in this article.
