Various forms of the Hydtopunch® exist: they vary in the method used for <br /> ' sample collection. Hydroptmcb 10 uses doe body of the hydroptmch to collect and retrieve <br /> the sample. Hydmptmch HO allows for the collection of water samples using a bailer <br /> lowered within the CPT rods or drill atom. <br /> 3.5 Sounding - the entire series of penetradort testa performed at one location. <br /> 3.6 Friction Ratio - the ratio of friction resistance to cone resistance, expressed in percent <br /> 3.7 Fricdat Resistance - the tesistaace to penetration developed by the hictio t sleeve, equal <br /> to the vertical form applied to the sleeve divided by in stuface area. lois resistnta consists <br /> ' of the stmt of friction and adhesion_ <br /> 3.8 Differential Prue Pressure Ratio - A calculated parameter equal to the excess pore <br /> pressure measured behind the tip divided by the soon of the tip resistance (corrected for pore <br /> ' pressure effects and the total overburden stress). Used in combination with the end-bearing <br /> resistance to infer lithology. <br /> 3.9 Pae pressure - Water pressure in the fatnation. <br /> ' MZ103.1&95WVr/30PlS0P102 <br />
