Mechanics of Seafloor Penetration by an Axisymmetric Tube: Static Penetration Studies.
NTIS: PB 196 605 :15 pages
The Bureau of Mines studied the penetration of a slender cylindrical tube into a sand bed, simulating seafloor material under the application of a static load. The factorial experimental design was based on three factors: tube diameter, geometry of penetrating bit, and seawater saturation of sand, all of which were found to be significant in influencing the depth of penetration. The geometry of the penetrating bit, or shoe, is of major significance in the mechanics of penetration and should be considered the most important factor for additional study. Linear regression analyses of the load- penetration data show that the relationship is linear.
