Abstract

The compaction process of loose soils mineral skeleton is influenced by many factors, e.g.: vibrations, overloading and water flow through soils. The aim of the present paper is to asses significance of the last factor. In particular were studied the effects of water filtration on changes in the compaction of the mineral skeleton of alluvial sands, and on decrease in hydraulic efficiency of infiltration ponds in the Warta river valley, in areas of water intakes for the city of Poznań. Moreover, experimental studies on the analysis of factors responsible for the compaction process in fine-grained non-cohesive deposits were also conducted (within research project no. NN 307 3526 33). It was found that, along with other mechanisms, water filtration process is responsible for the total compaction of the mineral skeleton in loose deposits and affects minimum time limit required for the significant structural reconstruction in such soils. The experiment allowed to extend the spectrum of factors affecting changes in the position of the mineral skeleton in the analysed deposits, as well as provided opportunity of assessment of wider range of dynamic of changes than in natural conditions
