Zusammenfassung:	The paper presents the results of calculations of the sampling fluctuations in Pb–LAr electromagnetic sandwich calorimeters. The GEANT4 package was used to generate showers initiated by electrons with energies E 0 from 20 to 500 GeV. It is shown that the dependence of the sampling fluctuations on E 0 and the thickness of the lead absorber x can be described by the formula kx b / . The exponent b weakly depends on the LAr gap width d and is close to 2/3 and k = 0.1985−0.0363ln d [mm].
