Method and apparatus to generate shear wave signals and measure seismic parameters in penetrable media |
摘要 |
<p>This invention relates to a method for producing high energy horizontal polarised SH signals. SH signals are used to estimate wave velocities in SCPT and other in-situ geophysical tests requiring generation of SH seismic signals. The process improves upon existing methods of generating SH signals by introducing a new load-decoupling system capable of isolating applied loads from a beam-source system as well as the determination of the optimum load to generate the maximum shear wave amplitude. This invention further relates to a new source design, which improves upon existing methods of measuring offset distances to calculate seismic wave velocities. <IMAGE></p> |
