ABSTRACT



Results of measurements of a vertical deformation of soil of four forest site types, i.e. fresh mixed coniferous forest (fMCF), boggy mixed pine forest (bMPF), moist mixed broadleaved forest (mMBF), and moist broadleaved forest (mBF), using a plate bevameter and taking into account different moisture variants, are presented in this paper. The moduli kc, kφ, and n of Bekker’s equation were determined. The soils were grouped according to their resistance to vertical deformation through agglomeration using the Ward’s method. The Bekker’s equation moduli were determined once again for separated clusters.

Key words: forest soil, Bekker’s equation moduli, agglomeration.
