Determination of Elastic Properties of In-Situ Rocks in Permafrost Regions (Ob Opredelenii Uprugikh Svoistv Porod v Estestvennykh Zaleganiia v Oblasti Mnogolentnei Merzloty).

摘要

Seismic prospecting methods applied in permafrost regions for determining the elastic characteristics (Modulus of elasticity, shear, and Poisson's ratio) of in-situ rocks and soils are substantiated. Peculiar wave patterns established by seismic prospecting in the arctic regions are examined. Typical wave patterns are analysed using the ultrasonic test data obtained on three-dimensional models of natural materials. (Author)
