| Abstract | |
The performance of instrumented pier in unsaturated and collapsible soil was evaluated. In order to study it, six instrumented caissons were performed to obtain the bearing capacity, settlements, the load transfer curves, and the separation of the base resistance and skin friction. Static load test were carried out with natural and saturated soil conditions to quantify the influence of moisture on the behaviour of pier. Field and laboratory tests were performed to obtain the soil resistance parameters and moisture content variation \"in situ\" in order to study the bearing capacity using unsaturated soil concepts. Numerical simulations were carried out through the model proposed by MACHADO (1998) to predict the behaviour of pier built unsaturated soil at the experimental field of foundations of USP/São Carlos.
