Compressional Wave/Shear Wave Seismo-Acoustic Probe.

摘要

The prototype seismo-acoustic probe represents the first version of a self-penetrating seabed probe system designed to measure the compressional and shear wave parameters of the seabed sediment. Several new and untried technical features and operating concepts were incorporated in this design to achieve the desired measurement objectives. Taking these broad factors into account, the basic probe system design has good technical merit and a very good potential for becoming a practical and productive seabed probe which can be improved and developed for widespread use. The initial shipboard and seabed tests revealed that certain physical design features of the prototype model should be modified to improve the ruggedness and reliability of assembly and operation. Other design features associated with the acoustical performance of the probe must undergo revision in order to achieve productive seismo-acoustic measurement results. The prototype probe system has provided an excellent test bed by which the overall application concept could be tested and evaluated. Based upon the test results from the first sea trials, this equipment has the potential to be modified to incorporate certain necessary and desirable changes and to be used as the basis for further tests and perfection of the self-penetrating seabed measurement technique.
