BORING LOG LEGEND <br />SAMPLE TYPE GRAPHICAL <br />SYMBOL SAMPLE DESCRIPTION <br />AUGER <br />CORE <br />SAMPLE COLLECrED FROM AUGER CUUINGS, NO FIELD <br />MEASUREMENT OF SOIL 5TRENGTH. (DISTURBED) <br />ROCK CORE SAMPLE: TYPICALLY TAKEN WITH A <br />DIAMOND-TIPPED CORE BARREL. TYPICAUY USED <br />ONLY IN HIGHLY CONSOLIDATED BEDROCK. <br />GRAB <br />SOIL SAMPLE TAKEN WITH NO SPECIALIZED <br />EQUIPMENT, SUCH AS FROM A STOCKPILE OR THE <br />GROUND SURFACE. (DISTURBED) <br />NSR 0 <br />SPT <br />SH <br />VANE <br />CAUFORNIA SAMPLER: 2-1/2 INCH I.D. SPLIT BARREL <br />SAMPLER, UNED WITH 1-INCH HIGH BRASS RINGS. <br />DRIVEN WITH SPT HAMMER. (RELATIVELY <br />UNDISTURBED) <br />NO RECOVERY: THE SAMPUNG AlTEMPT DID NOT <br />RESULT IN RECOVERY OF ANY SIGNIFICANT SOIL OR <br />ROCK MATERIAL <br />STANDARD PENETRATION TEST: SAMPLER IS A 1.4 <br />INCH INSIDE DIAMETER SPLIT BARREL, DRIVEN 18 <br />INCHES WITH THE SFT HAMMER. (DISTURBED) <br />SHELBY TUBE: TAKEN WITH A THIN WALL SAMPLE <br />TUBE, PUSHED INTO THE SOIL AND THEN EXTRACTED. <br />(UNDISTURBED) <br />VANE SHEAR TE5T: SOIL STRENGTH OBTAINED USING <br />A 4 BLADED SHEAR DEVICE. TYPICAUY USED IN SOFT <br />CLAYS-NO SAMPLE RECOVERED. <br />COLUMN DESCRIPTIONS <br />DEPTH: <br />SAMPLE: <br />BLOW COUNT: <br />POCKET PEN.: <br />GRAPHIC LOG: <br />DRY DENSITY: <br />MOISTURE CONTENT: <br />LIOUID LIMIT: <br />PLASTIC LIMIT: <br />PASSING #200 SIEVE: <br />UNCONFINED SHEAR: <br />Distance in feet below the ground surface. <br />Sample Type as depicted above. <br />Number of blows required to advance the sampler 12 inches using a 140 Ib <br />hammer with a 30-inch drop. 50/3" indicates penetration refusal (>50 blows) <br />at 3 inches. WH indicates that the weight of the hammer was sufficient to <br />push the sampler 6 inches or more. <br />Approximate shear strength of a cohesive soil sample as measured by pocket <br />penetrometer. <br />Graphic Soil Symbol as depicted on the following page. <br />Dry density of an undisturbed or relatively undisturbed sample in lbs/ff. <br />Moisture content of a soil sample, expressed as a percentage of the dry weight. <br />The moisture content above which a soil behaves as a liquid. <br />The moisture content above which a soil behaves as a plastic. <br />The percentage of the sample finer than the #200 standard sieve. <br />The shear strength of a cohesive soil sample, as measured in the unconfined state.
