摘要：Apparatus includes a transportation structure for generating elliptically
polarized shear waves in a soft earth medium. A suitable carrier includes a jack assembly (20,22,24) for transporting shear wave apparatus that includes a telescoping tube (16) for
reaction massearth engagement. The shear wave apparatus, including a major or lower reaction mass (32) and a passive top reaction mass (72) is raised and lowered by the jack assembly (20,22,24) into operative position while the energy-coupling telescoping tube (16) is extendably forced into an earth medium so that, during shear wave generation, the vibration source or reaction mass (32) is continually imparting shear wave energy into the progressively extending telescoping tube to effect continual energy coupling into the surrounding earth medium. The reaction mass (32) is preferably driven by a plural hydraulic actuator system that imparts elliptically polarized vibration to the telescopic tube (16) which, in turn, imparts elliptically polarized shear waves into the surrounding earth medium.
