VARIABILITY OF PHYSICAL AND CONSOLIDATION TEST RESULTS FOR RELATIVELY UNIFORM CLAY SAMPLES RETRIEVED FROM OSAKA BAY

摘要: ABSTRACT Samples collected from both Holocene and Pleistocene layers in Osaka Bay were examined this study. The objective of study is to evaluate variations soil parameters a sample length about one meter. retrieved samples EL. (elevation) -37.5 -38.5 m EL.-125.5 -126.5 m with meter divided into every 25 mm long trim consolidation specimens. Variations obtained laboratory tests evaluated. Clay microfabric was also evaluated by scanning electron microscopy (SEM) mercury intrusion porosimetry (MIP). clay are relatively homogeneous variation coefficient CV range 0.025 0.12 for the (e, p′c, Cc cv). void ratio e only 0.056. In contrast, values other significantly greater than this, but average less 0.1. It can be concluded that natural deposits dealt These mainly influenced sedimentary environment. Even said homogeneous, because specimen size sufficiently large consideration microscopic heterogeneity SEM MIP.
