Penetration Logging Methods and Equipmentented. The solution of a problem is achieved on the basis of combining the soil static penetration test and nuclear logging methods. The first experimental study on the application of the nuclear penetration logging method was started in 1962. The group of methods, which were tested and included in骚扰 发表于 2025-3-27 16:20:07
Theoretical Basis of Penetration Logging Testsdulus of compressibility and coefficient of inner ground friction is discussed. Solutions based on the theory of ultimate equilibrium, .mplacement of a spherical probe into an infinite elastic medium, imbedding of spherical sound in elastic media and taking into account creeping in time and a two-di比目鱼 发表于 2025-3-27 18:15:29

Application of Penetration Logging Techniques for Geoengineering Exploration penetration logging technique are discussed. The practical application of penetration logging methods in engineering geological and hydrogeological mapping for irrigation and drainage projects in the Alma-Ata (Kazakhstan), Kizil-Orda (Uzbekistan), Saratov (Russia), Kiev (Ukraine), Neman River (Belo细节 发表于 2025-3-28 05:21:16
Stable Isotopes in Study of the Global Hydrological Cycleng stable and unstable isotopes of individual elements, in particular by determining the variations in their abundance. Isotope geology deals with both stable and radioactive isotopes. In this chapter the distribution, hydrogeochemistry and geophysics of naturally occurring stable hydrogen and oxygeBrain-Imaging 发表于 2025-3-28 08:16:48

Radiogenic Isotopes in Dating of Natural Waters and Sediments .U, .U, .Th, .Th, .Th, .Ra, and .Ra) in natural waters are discussed in this chapter. Methods of dating surface waters, groundwaters, closed reservoirs and bottom sediments are analysed. The values of the radiogenic isotopes in waters are practically independent of chemical factors. It is mainly de
