     a series of empirical equations between several geotechnical and rock mechanical characteristics are determined on eleven-site executive datum. geologic notations and statistical discussions are used for arrangement and intermixture of datum (laboratory test results and tests in boreholes). because of many parameters have an effect on soil and rock mechanical and chemical behaviors, there are tried to neglect less important parameters. by determination of empirical equation, we can suitably presume of other parameters. empirical equations are obtained by relating following parameters:

    1- percentages of sulphat, chalk and ph in soil.

    2-dry unit-weight, specific gravity and normal unit-weight.

    3 -water content (normal) and water content (optimum).

    4 -standard penetration test (nspt) and allowable bearing (qu).

    5-rqd and lugun (permeability coefficient).

    6 -rqd and sampling depth in rocks.

    7 -coefficient of consolidation (cv) and coefficient of compressibility (cc).

    8 -others.
