The aim of the study is to obtain the variation range of the filtration coefficient of the upper (organic) forest soil layer with its density change caused by harvester and logging machines traffic. This article presents laboratory results of the Filtration coefficient of forest soils to its density. The studies were carried out in the laboratory of the Department of Logging Technology jointly with the Department of Timber Land Transfer, St. Petersburg State Forest Technical University named after S.M. Kirov. Hundred samples of soil picked in summer period 2013 near LLC «Kirishi-LESPROM» in the Leningrad Region were tested. Experiments were carried out according to standard methodology regulated by RF State Standard. Hundred soil batches, each is about 400g in the dry state, were investigated. Dependence of Filtration coefficient of forest soils to its density was acquired with and according to experimental data results. As well as filtration coefficient variation limit was assign. This article presents regression relationship valuation of organic forest soil filtration coefficient. Regression relationship is based on experiment's outcome and presents as exponential function. As well confidence interval limit (p = 95%) for the filtration coefficient is assigned. [ABSTRACT FROM AUTHOR] |
