South Pass, core B-2, m ( ft), remolded. sediment possibly disturbed (or a poor laboratory test, malfunctioning of the consolidometer) but not remolded in the laboratory by standard testing procedures. Void ratio determinations on samples from the same approximate depths yielded values of , considerably closer to the void ratio values found for the sediment to depths of . m below the mudline. Bryant and others (1974) have attributed the "sensitive-like" nature of the e-log p curves (virgin curve which is concave up) to be characteristic of the Gulf of Mexico submarine sediments with void ratios greater than about A sample from a depth of m (core B-1) with an initial void ratio of less than was consolidated to a load of ^ kPa. The e-log p curve shows a broad recompression curve up to a preconsolidation pressure of X10^ kPa which is quite unlike the e-log p curves of the much higher void ratio (high porosity) overlying sedi- ment (fig. 37). Clearly this material represents a consider- ably greater degree of natural consolidation than the high void ratio sediment. Noteworthy, however, is the fact that sensitivities, determined by shear strength tests to depths of approximately 150 m, ranged from slightly less than 2 to Figure 36.âVoid ratio versus logarithm of pressure.
