    Oedometer Testing - Soil Analysis

    Hello all

    I was wondering if any had a background or understanding on soil settlement/consolidation testing specifically oedometer testing.

    My understanding is that we simply measure displacement vs time however I have been given the following data:-

    I dont understand the Dial Reading values which are shown in mm.

    I would interpret this data as at 0 min the displacement was 7.82mm, at say 4 min the displacement is 6.78mm - but why are the values for Dial Readings getting smaller I would have thought that as the soil compressed then the displacement values would get larger.

    Can anyone help shed any light?

    Thank you.

    Soil Analysis Consolidation and Oedometer Testing

    Without pressure applied details, local specifications, end goal of performing soil testing - not sure what you need..

    However, here is a document that maybe helpful.

    Tell me and I forget. Teach me and I remember. Involve me and I learn.
