Vibration radiation
Lankelma was requested by Geodelft, as part of the CONVURT Consortium, to perform dual seismic CPT tests in Regents Park, London. The purpose was to investigate the vibration radiation from underground railways and the possibilities of reducing them.
Seismic cone
The seismic cone is a specialist tool which incorporates a dual seismic cone with the triple element geophone separated by either a 1.0m or 0.5m.
The advantage of this cone is that it incorporates a standard piezocone on the tip so the seismic testing and the CPT can be performed at the same time.
Performing these tests enables a full soil profile to be obtained, together with interpreted shear modulus values Gmax, undrained shear strength and relative density values of the soil.
