Abstract (en)
[origin: EP1956147A1] A method for local seismic protection of building and/or built areas and/or of foundations and building adjacent zones, consists of interventions for injecting into the ground products, also expanding ones, effective even in the presence of water and/or humidity, and directed through special injection pipes (8) to act on the portions of ground (9) that require a reduction in the potential seismic effect towards overlying structures. Such portions of ground are localized and monitored with predetermined frequency and geometries before, during and after said injection interventions through a series of seismic sources (6) (energizers) and series of receivers (4) (transducers) for geophysical instrumental measurement connected to multi-channel acquisition systems (5) (seismograph/accelerometer). The attenuation of seismic effects is controlled by an increase in the mechanical features (elastic moduli) of the treated ground, in turn influenced by the progress of the surface Vs wave speed in the ground, essential parameter for the evaluation of the potential local seismic attenuation or amplification phenomenon.
