LABORATORY TEST RESULTS In order to determine geotechnical parameters of the sediments and samples taken from exploratory boreholes and test pits, some laboratory tests [4,5,6] were carried out and results have been provided in tables 3 and 4 for the pits (TP-F1 to TP-F5) and exploration boreholes (BH-22) to (BH-24), respectively. Evaluation of laboratory results of these loose and weathered soils which are also sensitive to moisture shows that as their compressive strength has direct relationship with modulus of elasticity, and in in-situ tests these strengths are 3 to 4 times than the strength of the surface soil or the marly layer which is sensitive to water, the laboratory test results generally control field test results and have an appropriate trend, in weakened scale. If due to the cementation of natural undisturbed rocks, their internal friction angle is considered similar to these soils, considering the necessary conservativeness, cohesion values of the natural soil in in-situ case is at least 1.5 to 2 times as the above-mentioned loose, disturbed samples.
