Strength Characteristics of Compacted Soils

摘要

This research was conducted to obtain data on the strength of soils considered for use as embankment material under conditions of 90% and 95% relative compaction and moisture contents ranging from optimum to a zero air voids condition, as determined by the California Impact Test and by the new California Soil Moisture Density Apparatus. Results attained indicated that strengths at relative compactions of 90% and 95% as determined by the California Impact Test were consistently higher than those determined by the California Soil Moisture Density Apparatus. Emphasis was placed on the determination of embankment heights that could be safely constructed from several materials under various conditions of moisture and density. Five soils were tested for strength characteristics at varying degrees of compaction and moisture and were found theoretically able to support embankment heights ranging from five to over 1000 feet.
