1. A method for monitoring the state of a foundation supporting a structure and embedded in the ground, comprising the following steps: acquiring, using a set of sensors placed on the structure, a set of measurements (m i1 ,m i2 ) relating to the foundation and/or to the structure, according to a determined mode of acquisition; computing, from said set of measurements, a set of state indicators (i j1 ,i j2 ) characteristic of an embedding stiffness of the foundation; and performing a comparison between a set of values deduced from the set of computed state indicators and a set of thresholds.
