Popis: The method involves arranging a source (4) suitable to generate seismic waves within the second geological layer (5) whose rigidity is intended to be measured. The source of seismic waves is activated. The seismic signal is detected by sensor (8) coupled with the free surface (2). The shear velocity of the elastic waves in the second layer is determined from the seismic signal so as to indicate the rigidity of second layer. USE - Method for determining rigidity of geological layer underlying the foundations of building. ADVANTAGE - The rigidity of geological layer can be determined easily. The velocity of the elastic waves in the subsoil can be measured easily while improving the elastic parameters such as Young's modulus and the rigidity modulus. The need for large number of sensors for measuring the velocity of the shear waves can be eliminated while reducing the cost for measuring velocity of the shear waves. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for system for determining rigidity of geological layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating process for determining rigidity of geological layer.
