Static load tests on raft on rigid inclusions
Static load tests on raft on rigid inclusions
A full-scale experimentation of static loading tests on square footings on rigid inclusions has been performed in the framework of the research project ASIRI+. The purpose of this experiment was to assess the effect of the presence of a load transfer platform between the shallow foundation and the rigid inclusions on the behaviour of the footing and of the improved soil. To do so, three configurations of load distribution platforms were tested, under different loading conditions (vertical catered, vertical with eccentricity, horizontal-vertical combined loading). Preliminary load tests on instrumented isolated rigid inclusions were carried out to study their behaviour under compression. A complete instrumentation solution was designed and implemented (including strain gauges, inclinometers, total stress sensors), to assess in details the distribution of the load between the soil and were, This publication presents the geotechnical context of the study, the instrumentation implemented, and the different load cases. Results as then presented, and conclusions are drawn, allowing a better understanding of the behaviour of the improved soil under the footings.
