Maximum dry unit weight of soil

| | 4 comments


And more importantly, you know where the optimum is, so if the field conditions are too dry or too wet prior to compaction, you can adjust accordingly if needed. Next we run gnuplot from the command line Linux Debian OSview with the ImageMagick programme display and capture all output to stats. Therefore, it is logical to interpolate between these points, so my vote would be to use the cubic spline approach, including all points, rather than use the linear regression model. But that is the general idea. Finally, which curve is the most appropriate? This means you could either measure more points to reduce uncertaintychoose a different fit, etc.

  • It is peak density of the soil taken in the driest state. The maximum dry unit weight is determined using laboratory method for the standard proctor test.

    Soil classification

    From the. The dry unit weight distribution for peat, organic soil, and clay are presented later in Figs. . The maximum dry unit weight of soil was determined by placing the. Note that the increase in the unit weight and the reduction in the moisture maximum dry density, vibrations will result in the rearrangement of the soil grains.
    Data File Using GnuPlotwe look at: 1 linear regression using quadratic forms and 2 interpolation between points using cubic splines.

    It is also clear that if a dispute were to emerge on a construction project, the Contractor would have a legitimate case. Is this a homework problem?

    One of the things that struck me about this question is that the course booklet states the maximum value is higher than the results of the test, that is:. Next we run gnuplot from the command line Linux Debian OSview with the ImageMagick programme display and capture all output to stats.

    The optimum moisture content is defined as the moisture content where you get maximum dry unit weight.

    So plot moisture content (w) vs dry. Typical values of soil dry unit weight for diffenet types of soils. because we are interested in the weight of solid soil particles in a given volume, optimum moisture content, mopt, for the maximum dry unit weight, (γdry)max.
    However, if we want to interpolate, you need to decide on a fit.

    Using GnuPlotwe look at: 1 linear regression using quadratic forms and 2 interpolation between points using cubic splines.

    So let's put this under scrutiny, by examining the data with commonly accepted curve fitting methods. Email Required, but never shown. Columns 1 and 2 are the data given. From inspection of the Moisture-Density plots, the maximum values from the various curve fitting methods do not exceed the measured test value, only the position of the optimum moisture content changes.

    When a higher value is used for acceptance of the Contractor's work than was actually measured in the laboratory, there must be a valid reason for it. GnuPlot Source File The gnuplot script, density.

    Unit Weights of Soil. Symbols and Notations γ, γm = unit weight, bulk unit weight, moist unit weight . (γd)max = dry unit weight of the soil at its densest condition. For a given compactive effort, the maximum dry unit weight occurs at an Compaction is a process of increasing soil density and removing air, usually by.

    The weight and volume of a soil sample depends on the specific gravity of the soil. The peak or maximum dry unit weight usually corresponds to saturation.
    One of the things that struck me about this question is that the course booklet states the maximum value is higher than the results of the test, that is:.

    1. The relationship could be ball-parked as quadratic, so fitting it see image below as such yields.

    2. Related 4. So let's put this under scrutiny, by examining the data with commonly accepted curve fitting methods.
