WebAbstract. The Yellow River Estuary is a typical constructive delta with a complex sedimentary structure. To analyze the physical, mechanical properties, and structural characteristics of the surface sediments in the delta, reveal the sedimentary environment and avoid geological hazards, cone penetration test (CPT) is used for nautical in situ … WebAMDRILL, Inc. carries out all Cone Penetration Tests (CPT) using an integrated electronic cone system, (see figure CPT below.) The soundings are conducted using a 20 ton capacity cone with a tip area of 10 cm2 and a friction sleeve area of 150 cm2 . The cone is designed with an equal end area friction sleeve and a tip end area ratio of 0.85.
